"Mark,
It wasn't entirely "difficult" in the sense that I never got stuck on a certain step. But it was quite involved.
I followed the procedure in the shop manual. The executive summary is you must remove the hood since the hinge…"

I’m struggling with my TV rod adjustment. I’ve been trying to adjust it as per shop manual, but it’s still not OK. When cold, it shifts smoothly through all four gears, when hot, it hesitates (lots…Continue

"Hi Kenneth,
How difficult was it to get to and replace the evaporator core?
I've heard something about an opening in the inner fender?"
"Hey Mark,
I'm in the midst of converting my 63 to R134a and replacing lots of components. I replaced almost everything, including the evaporator, with new parts. And I still have been chasing leaks.
A friend brought his freon sniffer over,…"
"Are you setting the TV rod with the throttle rod disconnected from the carb? The vacuum dash pot hods the throttle open just a little bit. "
"Trans was rebuilt about 2 years ago and all internal seals were replaced. The problem started when I changed the fluid (type A). It was shifting fine before but with the fresh ATF, 2-3 shift was a bit too late to my taste so I decided to reset…"
"Its not the TV rod, the trans is in need of a rebuild. Fluid is bypassing internal seals when hot. Try adding Lucas trans additive. "
" You may have the the TV rod adjustment close because it shifts fine when cold. The Fluid gets thinner when it heats up . I had a similar problem running Dexron VI which is thinner in viscosity than Type A or Dexron II or III. I ran 5 Litres…"
TV rod adjustment 1963 Cad
I’m struggling with my TV rod adjustment. I’ve been trying to adjust it as per shop manual, but it’s still not OK. When cold, it shifts smoothly through all four gears, when hot, it hesitates (lots of revs) to make the 2-3 shift and most of the time there’s no 3-4 shift. I’ve tried and test drove time and time again yesterday, but with very limited results. Fluid level is OK, so I suspect I’m doing something wrong with the adjustment. Can someone knowledgeable in this field pls give me a simple…See More
"It's possible that the evaporator core is leaking. There are electronic freon detectors that "sniff" the air and beep when they detect freon (& other gasses). These are good for finding leaks from inside the A/C box through…"
1963 AC evaporator core leaking?
Hi all,Again I have issues with my AC system. Had it refilled recently but within a few days the system was empty again. The AC mechanic added tracer fluid to check for leaks, but there are no visible leaks anywhere. I’m starting to think it’s the evaporator core as this is the only place that can’t be checked.From your experience, how likely is it that the evaporator core is leaking?And how easy (or not) is it to replace the core?See More

"Thanks! Like the color on your 64. You don’t see that very often."

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…
