  1. Currently I have 350/th350 in the car now. Are there companies that make driveshafts for this purpose (ready to ship with the correct specs) or will I have to measure? My main concern is having to go out and find a yoke from whatever vehicle I get the 4L80E out of and have it mated to a driveshaft especially if I have to buy a new one.
  2. For the guys who have already done a LS swap on their Montes I have a few questions. I am looking to switch over to a 6.0L and 4L80E, but my Monte is still has the factory set. 1) Did upgrade your front brakes and rotors because of the LS swap? If so, did you have to switch over to a bigger rim and tire? 2) Did you have to change out your cross-member to run dual-exhaust? 3) Is there a setup with the 4L80, whether it a long shaft or normal, that will allow me to use my current drive shaft?
  3. I've been looking at 12-bolt rear ends on Facebook and Craigslist and I came across a few, but I am unsure if I can use them. From the post above I am pretty certain that I will be able to use a rear end from a A-body. But I am seeing a some from (67-72) C10 trucks, (80, 82-92, & 88) Camaro, (78) Caprice, and a (69) truck w/ 6 lugs (??) Can I use any of these?
  4. Hey Mike, By chance do you have any rear-ends for sale for a 72 MC?
  5. 🤣🤣 I tried to send Mike Brichta an email to see if he still has rear ends for sale, but I got an error message stating he cannot receive emails. Are the 8.2" 10-bolt rear ends that bad off or is this about beefing up the rear-end? Lets say I am able to obtain a 12-bolt posi-rear end is it a direct bolt on or will I need to make modifications so that it will fit?
  6. Well jft69z the problem is finding a 12-bolt rear end or a 8.5" 10-bolt rear end that is in the price range of just replacing the parts on my rear end. I've called many junk yards in my are looking for a 12 bolt rear end and most done have them. If they do have them they want at least $1500 (non-posi) for the rear end and then I will have to convert that rear-end. The cheapest 10-bolt posi rear-end I've come across was $1000 (not even sure if it was an 8.5" 10-bolt) but I would have had to get it shipped to me. With my current rear end (with me spurging on parts) I am looking at about $1100-$1200 installed and that would include a "high-strength" alloy axle kit, richmond gear ring & pinion set, the Detroit TruTrac diffenential, and the miscellaneous thing like fluid, shims, and bearing. Couldn't speak on which rear end is more durable or better, simple because I lack the knowledge to make a quality case for either. To be honest I didn't even know a 10-bolt posi rear end was possible until reading post in this forum. What I can tell you is that I have no plans to race my car, but I do plan to rip up and down the highway every chance I get 😁.
  7. Thanks cny first gen 71 for the pic of the rear ends as it was super helpful aiding me in identifying the which rear end is on my monte. Blackhawk and MC1of80, I have a 8.2" 10-bolt rear end and I would like to go with the Detroit Trutrac, but I haven't been able to find one that fits my application on summit or jegs. When I searched the Eaton site the options that I was able to fine was posi limited-slip differential 19603-010, but I have a felling this is not the part you meant. I do plan to change out the gears when doing the differential and I am thinking about going with a 3.55 or 3.73 gear ratio. Which if I am understanding all of this correctly I will need a 3-series differential for this application.
  8. Hey Mike & MC1of80, Thank you both for the info. I will look into the Detroit Trutrac. Is there an easy way to figure out if my car has a 28- or 30-spline. Needless to say, I have a ton of homework to do before jumping into this because I have so much information to figure out. Thing I don't know but need to know: (If there is anything else please let me know) -> 8.2" or 8.5" 10-bolt -> 28- or 30-spline -> Gear ratio
  9. If I have a 10-Bolt non-posi rear end can it be converted into a posi rear end? My plan is to swap to a 700-R4 transmission and I would like to have a posi rear end to go with it. Is it as simple as dropping in a kit like this and boom you have a posi rear end? I actually don't know what size my 10-Bolt rear end is and I don't know much about this kind of stuff so any advice would be appreciated. https://www.quickperformance.com/GM-85-10-Bolt-Posi-Gears-Bearing-Kit-Package_p_20372.html
  10. Trying to figure out the best way to approach the restoration of my 72 Monte Carlo. I am not looking for showroom quality; however, I do want it to look nice while driving around. In this instance will it be wise to do a rolling restoration or a frame off restoration? The car has major rust issues in the trunk, but the rest of the car isn't too bad. FYI... I have most of the big sheet metal items to restore the trunk and rear quarter panels. Link to pics are below https://drive.google.com/folderview?id=0B06Pw4i_3FlranVmNEpNWEx3XzQ&usp=sharing
