Replacement Front Crankshaft Seal - 1964 Eldorado (429ci)

My mechanic is having difficulty sourcing a front crankshaft seal. Can anyone recommend a replacement front crankshaft seal, and where to purchase? Amazon has a few that I think(?) are replacements for a 64 Eldorado 429ci. A National with similar AC Delco seals listed. See link:

Amazon.com: National 351267 Oil Seal : Automotive

Does anyone know the OEM (GM/ AC Delco) part number to cross-reference for current available replacements? Thanks in advance.

Rock Auto has a SKF seal and a speedy sleeve kit as well.

I had provided this in an email but might be useful to others:

The original Engine Front Cover Oil Seal was in Parts group 0.213 with Part # 148 4702.

I have been using the SKF 19832 for 2 decades on my 64 with good luck. I show Rock Auto has them for $6 and some change.

I am sure there are other replacement brands and part #’s. I see Caddy Daddy has the seal # 19832 for $39! You got to love how proud Caddy Daddy is of some of their parts.

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,

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…
