im talking about the aluminum caliper big pbr brakes that came with my 89 iroc. i understand these brakes will bolt to a 3rd gen 10 bolt, what about a 4th 10 bolt? do they have the same mounting pattern?

 

anyone know? ttt

I can't answer your question, but if you have a 9 bolt why would you want a 10 bolt??? I assume you have a 9 bolt.

 

because its a 2.77 rear end, and im not gonna give 400+ for a 3 series carrier, then another 300 for 3.45 or 4.10 gears, plus another hundred or so for a rebuild kit when i got a axle to axle 10 bolt with posi and 3.42s for 225, less brakes.

 

i guess we will know in a couple of days. ill post results.
