Hey guys,

hope you can help me one more.

I'm wondering how the correct wiring of the AC-compressor ground should be. If you do it like in the original shop manual on page 13-45 (Fig. 13-32, marked red), the compressor does not have any contact to the ground, because of of the rubber shock absorber of the compressor. So there must be an additional wiring from the compressor to somewhere with ground. Currently my wiring is attached to the bolt where you can adjust the tension of the belt, but this is not very practical.

How was it originally in 1964? Do you know?

Jason, thank you for the photo. I think this solution is the best.
But in the shop manual page 13-44, Note 37a. (Compressor Removal and Installation) #6 the text is: 'Disconnect clutch coil wires and remove screw securing ground wire to compressor'
So it should be correct on the compressor.

As I found out, with some more investigation, one car does have the ground on the compressor, another on the right thermostat housing, another again does have a longer wire, which connected to a bolt on the engine block etc.

@ Dan: rubber mounts on the rear of the compressor?! I don't have rubber mounts there. Is it possible to take a picture?

Compressor switch feeds the compressor via black wire (page 13-26 in 1964 shop manual). Black/White wire on same connector ground to right side thermostat housing bolt from factory.

  Here is a lo res picture.. I'll try to find a better pictures:

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
