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

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,

-Samu

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
