12 bolt question...

a guy i know wants to get rid of his current set up, 12 bolt, full spool, 4.56's, all for a really good price 400 bucks

my question is, it is coming out of an olds cutlass, will i be able to use this rear in my 02 z28? what is the width of my stock 10 bolt flange to flange?

That's a great price, but it won't work in your F Body, as you need a housing that has a torque arm bracket designed into it. Bob

It could work if you can find an old SummersBrothers cover and arm.......

Well, many many years before KTRE started casting the new 12bolt centers with the torque arm mount..... SummersBrothers used to make a rear cover that incorporated a torque arm link for use in a 3rd/4th Gen F-body. And it worked, reall really well. I put a few in land speed record chassis' and quite a few street chassis' as well.

The thing is.... it would be a diamond in the rough to find one. Ever since Bob died I havent really seen that many around.

BTW, Bill and Bob Summers were the cats who defined what being "the ****" in the differential business is all about.... since the mid 50's. They are in a class of their own... and right next to Mark Williams.
