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.

I did mine working from inside with the glove box liner removed. Posted here https://6364cadillac.ning.com/forum/topics/recirculation-actuator-r...

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.

Ah, I see. I haven't had the pleasure of replacing that yet.

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…
