Tail Light Issue

I have an issue with my left side lower bulb in the bumper end housing portion. The bulb that operates the backup light. I can't get a bulb to operate although I do get 12V when I put my tester to that center pin inside the bulb housing. I even added some solder to the tip of the bulb contact to see if the buidup would help contact, but no go. The bulb does take a bit of effort to insert as if it is contacting the spring loaded pin.

U had this same issue and messed with the socket for a long time, but could not get it to work consistently - the spring at the base was just too old and had lost its springiness. I replaced the socket and all was well. I documented the process at the link below - it is really pretty easy and actually took much less time than I had spent fiddling with the original socket.

Trivia #34 - What % of 1963 & 1964 Cadillacs Came with Tinted Glass

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

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…
