Heater-Air Conditioning Vacuum Power Unit 1963 Coupe deVille
I am not having issues with with my vacuum unit but have been looking at what it would take to replace it if became necessary. Can the 2 nuts that hold it to the rear plenum be reached from the inside without removing the plenum? The rear plenum is very close to the firewall and it appears that space is quite limited to access the nuts on the backside of the plenum.

The vacuum unit you are showing has already been replaced. The unit I am speaking about controls the flow of air between the floor/ac ducts. It is mounted inside the rear half of the heat/ac assembly and the retaining nuts are facing the firewall.

What % of 1963 and 1964 Cadillacs came with the optional "soft ray" tented glass? 1963 & 1964 were very close, so if you get one you will get the other. Need to get it within 3%. So, who will…Continue

1963 RHS A/C kick panel - photos needed

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

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…
