Not much to modify on the firewall really, the pedal assembly mounts under the dash. Chevelle pedals are a perfect fit. You may want to look into a Tremec TKX 5-speed transmission too. They're designed to fit in place of factory 4-speeds, require no floor mods. Plus they shift like butter & have a much higher torque capacity & RPM capacity than original 4-speeds. I've always had good luck with Centerforce clutch assemblies too, and they can handle well over 600 HP with their dual-friction disc setup. Lastly, a hydraulic clutch system would be my recommendation as well. Simplifies installation, gets rid of all the sloppy mechanical linkages, and the need for the Monte only frame mount bracket for the Z-bar (they're available thru aftermarket though, and originals can be had thru e-bay sometimes). I mount the fluid reservoir right behind the brake booster, barely noticeable. I used Silver Sport as the supplier for my trans & hydraulic system for my Camaro. They have a real nice hydraulic setup that fit perfectly (for the F-body Camaro, but they have stuff for us here too), and used an OEM type throw-out bearing that doesn't leak. I did a lot of research before hand, and it seems like a lot of other types were leak prone according to some reviews. They also have kits available with crossmembers, driveshafts, shifters, etc for an A-body. Best bet is to call them up and they'll help you decide what's needed. They're customer service is fantastic too, if you have any issues. I ran into a couple snags & they were right on top of it. Message me if you need more info, I'll send you my phone number.

Sorry about that, I updated the links/posts. They were active until pretty recent. It may be worth a call to them to see what they're doing to 're-engineer' the kits. They're pretty helpful on the phone and may still have the parts in stock to put a system together if someone needed one in the short term. Maybe I'll give them a shout Monday as I'm a little curious to see what they're changing.

This post below has info on the complete kit and shows what temperatures it produced in my car, on a hot humid day. https://www.firstgenmc.com/forums/index.php?/topic/32560-parallel-flow-condenser/#comment-275900 This post has the link to the S6 compressor, and different stages of 134 conversion kits: https://www.firstgenmc.com/forums/index.php?/topic/31585-replacing-air-conditioner-system/#comment-270508

You know how much I like working on cars too.... I like doing home maintenance stuff even less.

Early out on a Friday, not too terrible. I'll get you the info later tonight, pressure washing all the concrete around here today. Been needing to do it for about 4 years now, but working on cars got in the way.

* Galv coat would be fine, but anything covering it up will stop corrosion. * DD works GREAT, you'd love them. * If going thru the motions, get condenser and evaporator, matched set to work better. Sanden's are much better as far as efficiency, less horsepower to run, lighter, and won't leak out the front seal like the original A6's do. An alternative to that is a 'S6' compressor. They basically look like an old style, bolt in place with the factory brackets and hose manifolds, but have modern Sanden type internals (Nippon actually, the guy from Old Air told me recently. As you know, they're an OEM supplier, and quality is typically very good). If you want, I can find you links/info on the above parts. The place I use has a nice kit with everything in it, (evap, cond. compressor, brackets, drier, ald also includes the newer 'Barrier' hose for use with 134A).

Great job on the updates and pictures, thank you! A few thoughts to some of your questions below: * The brackets and under dash stuff- looks like it was zinc plated, or perhaps galvanized? I don't want to go through the trouble of re-plating everything like I did with the last build I just finished- So I was thinking of sand blasting and spray painting- but with what? galvanized coating, or grey paint? Any silver paint, galv coat, or Eastwood silver type paint (Cad coat, bare steel replicator, etc) would work. * I'd like to test the vacuum system/head/pods before putting it back in- hopefully that's a do-able task. Easily do-able. I use a vacuum pump for A/C work to provide a vacuum source. * Same goes with the instrument cluster- I'm pulling it apart to refurb it anyways. If not tied to a factory type restoration, Dakota Digital RTX gauges are an excellent alternative. Look stock, but much more versatile and functional * evaporator is really big. I wasn't expecting such a hefty girl in there. I've been half tempted to make some hose manifolds and suck it down to see if it'll hold vacuum- but I know better and should replace it so I dont' have to do the job again when the car is together. Hopefully it responds well to 134. Since it's already out, it may be a good time to replace it with a modern, parallel flow replacement condenser & evaporator. They're designed to be more efficient with R134. Systems I've converted have much better, measured duct temps with the new parts, as opposed to the originals. Now is the time, plus they look original. Are you planning to use a factory style compressor, or a more modern Sanden type?

Yeah, it is 😄

Looks like a lot of work ahead of you Alex, but it's to be expected for a car that old. Nice pictures, and as mentioned before, we like a lot of them around here. As Steve mentioned, Belden is a place that may make your project a little easier. Poke around all sections of their site though, there's plenty of info there that will help you. https://www.rustreplace.com/home/1970-1972-monte-carlo https://www.beldenspeed.com/

They (AAW) absolutely do have Monte specific, exact fit factory replica harnesses. They're in a separate catalog, not easily found though. Go to the link below, download (or view) the 'Exact Factory Fit' catalog, then go to the Chevrolet: Monte Carlo, Chevelle, El Camino section, pages 36-82. You'll find everything you need there. When I was going thru the research before wiring up my Monte, I looked at AAW, M&H, and Painless at the time. M&H was quite a bit more expensive, their lead time was in the tune of months as they make each harness from scratch, and were also more expensive than the others. Some vendors may stock common items from them, but you'd have to call to verify availability. Documentation was nil, as the gentleman said just use a factory manual, because that's what they're made to replace. I'm not knocking them at all, they've been around forever and quality is supposed to be top notch. AAW has all the documentation for their update type kits available online, their phone support is excellent, and their product quality is top notch as well. Their update kits are more for resto-mods, custom installations, people wanting more modern type fuses and more options as far as circuit protection (EFI, powered accessories, electric fans & fuel pumps, one wire alternator, etc). That's why you found a lot of the wires needing termination. That also allows you to run the wires to your liking & routing. That's the brand I use pretty much exclusively. https://americanautowire.com/pages/catalogs?gad_source=1&gclid=CjwKCAjw_4S3BhAAEiwA_64Yhtt40wCUHOKgTptX48AoSYD3Y1Jc2FAYv6GNYCX8Ro87C9mmTD2VphoC5JYQAvD_BwE

I've had good luck with NAPA starters. Lifetime warranty on the new and reman units.

What pages are you looking at in the Assembly manual for a '70 Dan? I see in the 70 manual, section D55, sheet A4 (page 534) shows a knob to be part number 3922525, that's under the 'floor console option'. When I go to the 4-speed transmission section, it shows a 2 piece knob. In the 1971 book, Section D55, sheet 7A-5, page 499 it shows a knob as part number 3992308. I googled the 1971 part number, there is a good discussion here about that stuff: https://www.yenko.net/forum/showthread.php?t=80719&page=2 https://www.chevelles.com/threads/muncie-shifters.75007/ 1971 1970

Depends on your settings. I'll give you a call when I get home later, see what you're having concerns about.

Can't even buy a coffee with that winner, 😄

The DMV and insurance company certainly blamed me, 🤣
