Hi everyone,

I just joined this amazing site so I have a lot to learn.  I just purchased a 1969 Corvette convertible and it has a Crate 350 engine so, obviously, it is not a numbers matching car.  I don't see any A/C components in the engine compartment but they could have been removed by one of the previous owners if they ever existed.

Is there a way I can determine whether, or not, my car had A/C from the factory?

Thanks so much, in advance, for any assistance you might be able to provide.  I look forward to being a member here and getting to know some of you.

Thanks again and God bless!

John

A/C cars would have several large holes in the firewall that non-A/C cars did not have. If the A/C plenum has been removed, it would be easy to determine if those holes had been covered/filled in. They would also have to change the console controls from A/C to non, to make it "look" correct. If you could post a pic of the passenger side of the firewall from the engine side we could help determine what it was. Thumbs Up

There are 2 braces under the passenger side dash and one on the driver side.  Your pax side console would have a small triangular extension down at the forward end of the console to cover the end of one of those braces. 

There were no vent knobs on the console of a/c cars.  You would have the recirc door in the pax side footwell.  No vent door in the driver side footwell. 

Also, a/c cars did not have the flow through vent system on the back bulkhead.  Just flat plates riveted in those rectangular holes.

You can see this in the assembly manual.  You should have one or get one.

An A/C equipped car will have a center vent below the wiper-washer switch. A car without A/C will just have a blank plate there with the Corvette letters.

Look for the extra belt pulley, or removal of bolts in exhaust manifold where mounting bracket was.

Thank you VERY much,

I was out running all day today but I will follow up and take a couple of shots of the passenger side firewall in the engine bay.  I'm already loving this site!  Thanks for taking the time to try and help me.  God bless!

Wow!  Awesome reply my friend!  Thanks so much for taking so much time to help!  I was running errands all day today and just had a chance to review your incredible comments.  I'll try to take a look at my car in the next couple of days to compare with your photos.  VERY helpful.  Thanks so much again!

Great advice!  However, my car has had a newer Crate engine installed and it has headers.  Therefore, I'm not sure how much they have changed this car beyond that.

Thanks for taking the time to help!  I really appreciate you!
