Jeff Dodson Posted January 15 Posted January 15 I need the expandable ducts. They seem to only sell in 6'ft pieces. I don't need 6'ft in the large or the two smaller ones 1 Quote
Dtret Posted January 15 Posted January 15 Double check The Parts Place I believe they sell 3 ft sections. 1 Quote

B-Man Posted January 20 Posted January 20 @Jeff Dodson, Who is the vendor associated with that diagram? And are the 70 to 72 Chevelle parts an exact (or close) replacement for the Monte Carlo? I've got my dash pad off and discovered a whole host of to-do items under and around it. Including a DIY duct work hack job. Even having that photo that you posted is helpful so I know what the goal is. 1 Quote

Main thing is measure your vents, Parts Place has them. I didn't order them yet. Got a few other things to straighten out 1 Quote
B-Man Posted January 20 Posted January 20 @Jeff Dodson, thanks. I dont see a link in your response. I went to the Parts Place web site and was able to navigate to Chevrolet Monte Carlo > Interior > DEFROSTER, HEATER FRESH AIR & AC DUCT HOSE It looks like they sell the various diameter hoses in 6ft lengths. I just need to figure out what diameters I need to replace all of the hoses under the dash pad. I dont see a reference for that. Thanks though! 1 Quote

MC-71 Posted January 20 Posted January 20 Okay this is what you need. 3 1/4 ID 24” long 1 3/4 ID 5” long 1 3/4 ID 12 1/2 long These are the stock measurements. You can find all these at NPD web site. One thing you need to remember is that they say 3” ID is correct. no it’s not call you order in and ask for 3” 1/4. They do sell the 3 1/4 in a 36” length. It is still a little tight but it will go. I know because it happen to me. Search for Heater Hose and Defroster. Let me know you make out. 1 Quote

MC-71 Posted January 20 Posted January 20 I only bought the larger one from them because this stuff is so expensive. The 3 1/8 will work, but its tight. If your dash is out put it on the duct deflector first. Maybe they are selling those sizes to fit their repro crap. Do you have the original ones. Ill post pictures tonight. I don’t remember where i got the 1 3/4. Might be amazon 1 Quote
B-Man Posted January 20 Posted January 20 @MC-71I will do some more research myself. Yeah, those prices seem a bit spendy for a simple hose. I appreciate their hussle though! 1 Quote
MC-71 Posted January 21 Posted January 21 You can get the 1 3/4” ID on Amazon. Search AA black flex battery vent hose tubing. It’s a 3’ pc at $14.99. Go with the one NPD sells. They sent me the 3” ID that didn’t fit. I called them and told them it was wrong. They said keep it and I asked for 3 1/4” ID they sent 3 1/8. It was tight getting it on but I made it work. Hope the pictures help. Buy the 1 3/4” right a way because I think they will be going fast. 2 Quote
MC-71 Posted January 21 Posted January 21 This is the reference number for the Amazon search for the 1 3/4 flex tubing. B07MWG5D37. 2 Quote
B-Man Posted January 21 Posted January 21 @MC-71, perfect. Thanks so much for that info. I will confirm what I need in the morning and get on order. 1 Quote
B-Man Posted January 27 Posted January 27 Ok, here is what I ordered ... This 3-1/4in ID hose from "Old Air Products" via Amazon. Looks legit and is more than I need. But material wise it's the right product 3-1/4 Inch ID Cloth Duct Hose AC Heater Defrost, 6 Feet Cloth [91-56C] Air Conditioning https://a.co/d/5oRhBKi Old Air Products also sells the 1-3/4in ID hose. But I ordered the one recommend above from Amazon since all I need is the 5in long section. Looks like a PO replaced the longer 1-3/4in tubing with a good, metal flexible hose. Wish I knew where that came from! A.A Black Plastic Flex Battery Vent Hose Tubing 1-3/4" ID RVs, Campers, Trailers (3 Foot) https://a.co/d/esBi9lp Quote
B-Man Posted January 27 Posted January 27 I'm just realizing that regular 'scat tubing' would undoubtedly work in this application. I used it for heat ducting on my plane years ago - duh!! Aircraft Spruce will sell in 3ft minimum length increments, for both the 1-3/4in and 3-1/4in ID for $78.90 plus tax and shipping. Dang, I wish I would have remembered that before I ordered off Amazon. I suppose I can cancel / return ... hmmm https://www.aircraftspruce.com/catalog/appages/scat.php Quote

Also, having worked in building construction, most HVAC guys can hook you up too. Quote

Again, Aircraft Spruce - or even Wicks - is what I should have done. Quote
