Re: 1966-76 9.375" Oldsmobile 12 bolt question
in the 9.3 I have not seen any 2,41 in 30 years....BUT I was not a BIG collector of full size car rears . 2.56 was most common then 2.73 ... a few 3.08 and 3.23 ratios and I believe I have NOT ever had a 3.42 either. Remember full size cars were luxury...and they had BIG cube motors and really just ...

Re: 1966-76 9.375" Oldsmobile 12 bolt question
The early 9.3 Olds 1966 -1970 will have 30 degree pitch axles and sealed axle bearings. The splines are usually NOT compatible with the 31 spline Ford axle spline pitch. The 1971 - 1976 era 9.3 Olds 12 bolt cover 12 bolt ring is a 45 degree axle spline pitch and should be compatible with the Ford 9&...

Re: 1966-76 9.375" Oldsmobile 12 bolt question
It CAn be done...BUT the tubes are smaller at 3" But early trucks were 3" tubes but I think all 9.5 truck rears were 3.25" tubes. Later they started to make the 8.5 / 8.6 tubes 3.25' so they can all use the same perches from 1/2" to 3/4" rears. We have a complete 2.73 rear 9...

Re: 76 monza
Just peel the GM stainless sleeve from the yoke and it will be ALL normal again 8610. If not your going to pay 3 times as much for a seal.

Re: bop 8.2 gear swap
Send pics of pattern before removing anything. You will need a larger splitter type bearing remover and a press is the best. I really do not like the heat thing as people usually get the bearing too hot and end over over tempering it... they it will fail. It is something you might do for a demo derb...

Re: bop 8.2 gear swap
.008 to .010 is perfect for GM used gears.

Re: bop 8.2 gear swap
Spacers in a BOP 8.2 rear are tricky. The stock posi units are a 2 piece set-up meaning the cone is one piece and the side gear sits on top. So if you do not have it centered enough in the case you could risk engaging only one piece and it will ruin the unit very quickly. so a 2 series flange is abo...

Re: Gear pattern
If you have any debris from when the ring was installed to the carrier...It would cause this. some time when the gear gets pulled or pressed on to the carrier the carrier body may get scraped from some material and then this gets lodged between the ring machined surface and the carrier machined surf...
