Can someone offer detail on the rear end in a 1964 Oldsmobile Ninety Eight Coupe Holiday? I am looking to change out the differential to a posi with a different ring & pinion.

 

The stock rear would be a 1957-64 Olds/Pontiac rear with the drop-out center section, similar to a Ford 9".

 

hey wedgewood, check out fabcraft serious stuff;spools, posi's, gearsets

 

This is a VERY strong third member -
They used these in the Gassers and Top Fuel dragster of the day... It was considered the best rear end of the time. Stronger than anything
1.875 pinion shaft huge bearing caps strong posi etc.

I have posi units and gears and rebuild kits BUT everything is very expensive. The older the rear gets the more money it is to restore. Jim

Do you have a posi unit and either a 3:90 or 4:10 ratio Ring & Pinion? If so, what would the cost be?

Thanks!
