When I got my 77 the compressor was locked up,I was going to replace it than found the lines were all dried up so they would need replacing also it would need to be converted to new gas. I've decided to get a A/C delete plate and put all the air conditioning parts in a box and save it if I ever sell the car. How many of you have deleted you're air?I'll be keeping the heat I live near Chicago so it gets cold here .

Thanks,Pete
Mine's a convertible and the compressor was already out when I bought it so the decision was easy.
I replaced the vacuum operated water shutoff with a home depot ball valve. The condenser was a disgusting mouse house. Took some patience to get all that out. The blower motor resistor was mounted in the condenser cover and will have to be mounted somewhere. Haven't figured that out yet. The replacement cover is pricey.
I don't know if a 77 has the air plenum flapper up in the passenger fender but if it does you might want to check it while you have easy access.
I had the passenger side dash, console and gauge cluster out to fix wiring & lighting problems. It was a good time to check all the vacuum connections from the a/c - heat control. Got the fresh air door to work properly. Found a bad defroster actuator - very little fun to get that out but I have a replacement on its way. Going to seal up the gaps in the plenum fittings while I have it all apart.
Took all that out today it was easy since I have the engine and trans out.I went thru all of the vac sys when I got her,right now I have most of the dash out waiting for my Daughters shop to paint vin code white.I had everything working before taking the engine and trans out.I took the fresh air vent out today the gasket was all torn ,ordered a new gasket and the A/C delete housing yesterday also the flaps that go on top of the A arms in the engine compartment I think it will be fun reriviting the 2 pcs of the vent back together.The engine compartment looks alot better now just got to wash it out and paint it .

Hi Sparky, I also removed the ac from my 77. I glassed the
firewall opening smaller and replaced it with a heater box from
a 69 non air for heat and defrost.
Put a ball valve in the line, just visible under the tank to stop the water in the summer.

Sparky - Thanks. I can look up the brand name on my wire loom device, but I doubt that you could use one, unless you have Vortec heads. They have bolts in the center that the device attaches to. If you do, let me know.
Tomorrow cleaning and painting the engine compartment .already looks better now that the A/C is gone .I'm going to take some pics so when the painting is done I can get all the wiring and vac lines back in.Did notice that the wiring going to the starter is all frayed so looked that up for a new one ,lectric limited #VSM7778AC just that pc. is 80.00 I guess the Vette tax is high on that wire!!!!
