72 Riviera Axle Width Needed

Pleeeeease does anyone know the width of a 72 Riviera axle..cant get to the car (building in progress) and need to order a 9" to go under it..I've searched every resource I can think of Thanks fellas Jack Liverpool England

 

I assume that you mean the axle housing width-- meaning what we call the "drum to drum" measurement?

 

thats the one

 

r
Reallyappreciate the input,but what is rear 'thread'...?

 

Ok thanks..will try and figure from there ?

 

You want the OVER ALL drum to drum NOT the flange housing end to housing end.

The only width that counts is your complete over all width with drums in place. Ford has a totally different brake offset than the Original riv rear etc. You need to have all your Duck in a row. YOU SHOULD WAIT....

crossing my fingers for you. Jim

 

Jim youre right. I'll wait and be sure Thanks

 

Save yourself alot of work and headache and just swap in a 8.5 its a direct swap and it had alot of aftermarket support

 

This thread is two years old.

 

Which 8.5 ' rear fits a 71-72 Riviera? I have been told that NONE of them will fit the E-Body Riviera....that the Ford 9" is the only option....I need to replace the rear in my 71 Riviera!!!

 

No it is not a 9 inch Ford. It is a post 70 9 3/8” BOP which technically is an Olds. There are some used gear sets but I do not believe there are any reproductions. There is a stuck thread on this topic.

 

Thankyou!
