Helping a friend restore his 66. It's the first Corvette he ever owned. He got it when he was 18 which he kept for several years but after he got married he sold the car. After 20 plus years he found the car and was able to buy it. It originaly had factory A/C but an earler owner had change it to a after market air. He wants to take it back to original. Can anyone tell me what year models will enterchange? I've found some 67 stuff, Are thier any part numbers that I should be looking for

Re: 66 A/C help
Hi Robert:
Can you provide more details about what is missing? For example, is it just the factory compressor or are the original evaporator assembly and STV valve gone too? What about the air handler on the passenger side of the firewall?
If all of these items need to be replaced, your friend is looking a very expensive project. Some of the parts are common to passenger cars of the era, but I believe that the evaporator assembly and the air handler may be unique to the Corvette. If all he needs is the factory compressor, those can be obtained from various rebuilders at modest cost.
To my knowledge, the 67 A/C system used a different compressor than the 66, and it used a POA valve instead of the 66 STV. I think the evaporator core was different too. However, I think the evaporator housing and the passenger compartment air handler were the same in 66 and 67.
BTW, there is an interesting lot of 1966 parts on ebay at the moment (item 250207337069), but unless your friend also needs the air injection parts for his restoration, this auction would not be a good match for his needs. -
Re: 66 A/C help
Thanks Joe,
We have everything that goes on the engine. We need everything under the dash and on the firewall. A/C boxs. Ebay item 120211213940 is what we need but for a 67. Don't want to bid on it if it's not right for a 66. RobertComment

Re: 66 A/C help
Hi Robert:
Hopefully someone else on the board can comment on whether the 67 parts are correct for 66. To my knowledge, the main changes for 67 were a different compressor and replacing the STV valve with a POA valve. I believe the valve change affected the design of the outlet tube on the evaporator core. Since you would most likely be installing a new evaporator core anyway, and STV valves are probably not hard to find, it would appear that the 67 parts in that ebay ad might be fine for a 66. However, I'd hate to be the guy who told you that if I'm wrong, because that ebay stuff will likely sell for big $$.
By the way, I can't quite tell if 100% of the necessary parts are shown in the ebay ad, but it looks like most of them are there.Comment

Re: 66 A/C help
Robert, the pic below shows the STV you will need. I believe they fit '64,'65, and '66, but not '67. They are not reproduced and won't be cheap. I have more pics plus some older film pics of the housing that I could scan if you want.

Re: 66 A/C help
Thanks Pat,
Is the STV the only thing different between a 66 and 67 system?
If you have some pictures of the 66 uder the hood box I can compare them to the pictures of the 67 boxs that I have been.Comment

Re: 66 A/C help
Robert - I suggest you get both a 66 Corvette Assembly Instruction Manual (AIM) and a 67 AIM and do the comparison of the two C60 sections. Have fun. PeteComment

Re: 66 A/C help
Robert, I believe the box and core are the same ('66 and '67) but the valves and thingies are different.
You might try looking in the LIC catalogue and see what parts are listed for the different years. It might help to have the AIM for '66 and '67. I could send a page from the '66 if you don't have.
The pic is the evap core box. I have more pics I could send you direct instead of taking up space here. Send me your email address if you want them.
