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.

1963 RHS A/C kick panel - photos needed
Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes
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,

Loud air moving sound within carb with cleaner removed

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
