Correct v-belt sizes.

Hi from the Netherlands.
Does anyone know the correct v-belt sizes for my Buick Regal? Power steering, altenator and ac.
I had seen them somewhere in the past but I can't remember where.
Buick 350. Vin. J.
Thanks for now and regards.

 

1976/1977 350J

alt - 9433744
p/s - 9433728
ac - 9433773

hope this helps.
David

 

Yes it helps.
V-belt guys. Good choise?

 

I run these. Don't know if there's any difference from my old 68-71 stuff..

 

Cogged on the outside. Is that better??

 

IDK, Supposed to flex around pulleys nicely. No issues for many yrs now.

 

They look nice & grippy!

 

I run the same ones as Mart.

 

It's funny because GM / Buick thought it was with the Alt. belt.

The 1976 belt is a non-cogged belt. In 1977 it changed to a cogged (notched) belt 1232791.

The '76 belt is larger and sits higher in the pulley than the cogged belt which is smaller and sits lower in the pulley,
that is why the 9433744 belt will fit both years. But the cogged belt is only shown to fit the '77 350J.
