I need to know if my rear brakes, rotors, calipers, backing plate and everything off of my 1988 IROC with a borg warner 9 bolt....

will swap over to a 1991 10bolt rear end with Richmond 3.73s, Moser 28 splined axles, alum stud girdle/cover, zex posi

I need to know.... as soon as possible please?

thanks

 

No! Not without extensive modifications.

 

what would those modifications be... or what would i need to buy to make it fit?

 

Modify the 10 bolt rear axle housing flanges to accept 10 bolt backing plates. Then install all of the parts to install the 89-92 PBR rear disc brakes.

I do not reccomend installing the old iron Delco-Moraine calipers on a rear axle upgrade.

If you wish more detailed information on this subject, drop me an email.

Thanx,andyZ28 andyz28@andyz28.com

 

Brakes are something most people overlook until after all the go-fast mods are done when they should be among the first upgrades we do to these 3400+ pound cars.

To do the swap and to do the swap RIGHT are 2 totally different things. Also, why do all the work involved to swap to those brakes when it's likely that those won't work worth a damn anyway? It looks like a good rear to use, now put good brakes on it.

Upgrade to PBR brakes which you can buy from a couple of people directly, or pend more time by piecing it all together yourself. I recommend talking to Andy about it since he's one of the most knowledgable board members on brakes.

this is so much work just to get some 3.73 rear end gears.... is there an easier way?

 

EB,

Who's selling the rear PBR kit these days (I don't think Andy is)?

EB, by the way I received my Spohn 1LE kit this past week, and I've again taken a peek at your pics. Very helpful.
