Technical rear end identification

will some help me i.d this rear end im pretty certain its a 8 inch or a 9 it has 10 holes for the gears and for mounting the axels it has 4 I don't know a lot about fords

 

I think it mite be a early 8 3/4

 

Looks Like early Olds, Pontiac, style rear.Not Ford or 8 3/4

 

Agree with the olds/pontiac

 

Olds/Pontiac for sure. 57-64 Diff. You have a three rib carrier, visible in you 3rd photo, somewhat rare and superior to the usual 2 rib. Looking at the leaf spring mounts prob a 57 Pontiac, worth some bucks to someone as a direct bolt in to 55-57 Chevys.

 

62/64 Olds/Pont. Rear in a 57 housing. The best ones out there. Nice find. Bolt in for 55/57 chevy or 56/62 corvette.

 

yea I should of know its not a 9 inch there more ovald and theres a 58 olds parked rite next to it but is it a good rear end are they strong is it worth getting?

 

I can't help. I saw the title of the thread, thought it was about something else.

 

Olds for sure! Runnin one now! Getting ready to do seals and bearings, fabcraft metal works seems to have the right stuff for em

Definitely Olds/Pontiac, definitely strong. Not only strong, but one of the coolest rears out there. I'm running one under my '38 pickup. That is...if I ever finish the damn thing!

 

Heck that was the rear end of choice for racers a long time ago. rebuild it and it will be nearly bulletproof

 

Funny you should mention the Corvette swap. I put a 57 Olds axle in my 57 Chevy sedan delivery in the 70's. BUT I also bought a third member,axles,and brakes off of a 60 Corvette shell that was sitting on blocks behind a gas station. Axles were already popped loose and when I got the pig out it ended up being a 3.08 open diff. Sure wish I woulda grabbed the whole car now...

 

What is the bolt pattern? 5 on 5 would be olds, like others mentioned.

 

I swapped the Olds/pont rear into my vette in 1967 because even a built 283 or 301 could break the chevy rear. They were very strong for the day. But with todays tire compounds, even the mighty 57/64 Olds/Pont of yesterday can easily break some decent power and traction. Today the only part I use is the main housing, With a 35 spline spool and axles. And I still have managed to twist the axles. WTF??

 

yea it is pretty cool looking rear one more question is it easy to get parts for or put a posi in it and change gears?
