Your question is beyond my level of expertise and I am not near my manual. I write only to suggest or ask if the hot idle compensator for your carburetor is functioning? It believe it should raise the idle speed when the…"

My AC compressor is leaking from the groove I marked with the little screwdriver. It is a broken shaft seal, correct? Where can I get a new seal and do I really need the seal remover tool J-9392 for…Continue

Comfort Control working as it should
Hi friends,after checking all the functions of my Comfort Control of my 1964 Fleetwood, everything is working as it should. The control of the temperature is working really well, except one thing... When the car is in idle on a traffic light or driving very slowly, the voltage of the alternator drops about 1.5 volts and the transducer does its job correctly and is switching to warm. On a hot summer day this is not very funny. I always have to shut off the A/C. If I raise the idle a little bit,…See More
"got mine from there, too. Since this modification it's not 100% seal but WAY better than before. Worth doing it. Just about one drop still hanging around ;)"
"I did the same modification end of May this year. For the first 300 mls it was perfect. After that it leaks a little bit. I would guess one or two drops after shutting down with hot oil for 1 hour. So totally acceptable. But it’s still very…"

"When the shop filled the system with R134a it was seal.I drove to a meeting with some friends to Austria with the AC on all the time at very warm weather and had a leak at the new shaft seal again. But probably the shop filled too much R134a. As I…"

looking for a 429 heat riser and cruise control unit
I am looking for a functioning heat riser valve and a cruise control for a 1964 Cadillac.In principle, the heat riser flap does not have to work. It is only important that the spacer / housing is not broken or has a crack.Cruise control does not have to work 100% either. The shaft bushings must not be knocked out.Does anyone have something like that lying around?See More

correct size of vacuum hose turbo hydramatic
Posted on November 2, 2014 at 5:19pm 1 Comment 0 Likes
I'm pretty sure anybody here knows the correct size of inner diameter of the rubber vacuum hose from the metal vacuum line to the vacuum modulator assembly? Mine is the original one, too old and does have several cracks now. Now the gear is not shifting anymore or let's say at too high rpm.
I don't have my car around me currently. So unfortunately I can't have a look by myself! :(

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…

My email is tbbahner@aol.com. I can send pics better that way. I have 2 intakes off of 1963 caddy's. I believe 62 to 65 interchange.

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,

Edelbrock Carb Block off Plates
Posted by Chase on March 12, 2025 at 2:05pm 14 Comments 1 Like
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…
