I have my pick of two rear ends to choose from for my car which should I get?
I currently have a 2.77 9-bolt with disc brakes, cast iron caliper


I can get either a 3.45 9-bolt with disc brakes, 11.7" rotor w/aluminum caliper The austrailian borg warner rear end


or

3.42 10-bolt 7.5" with disc brakes, 11.7" rotor w/aluminum caliper
found on the 90-92 cars...

Is either of them superior to each other?

 

the 9 bolt should be stronger.

 

9 bolt is alittle stronger but cost more if something goes wrong, but if you have a stock engine or one with some mods just go with the 9 bolt.

 

i'd go for the 9 bolt as well.....same thing i did
