I have a 9 bolt with rear disk brakes on the car and a 4th gen(LT1)rear complete with calipers and rotors.Is it possible just to take the caliper brackets off the 4th gen and slap em on the 9 bolt?

 

Nope, you need 9-bolt PBR caliper brackets.

 

The following link may provide some info, including where you may find the 9-bolt backing plates:

So all I need are the 9 bolt brackets and the brake lines?

 

Backing plates, lines (hard and flex), and parking brake cable. I've been told, but have no personal experience, that 9-bolts don't require shimming. However, you might keep that in mind if the carrier doesn't center over the rotor.

Yes...all you'd need is the correct backing plates and "maybe" new axle hard lines. I'd try the LT1 lines first and try to make them fit, they aren't that much longer than the 3rd gen lines.

Daz, sent you a PM about NE3G...

I guess it would be easier for me to just swap rear ends then beef up the 4th gen 10 bolt

 

I'd definitely keep the 9 bolt if you like the gear ratio you have, stronger than the 10 bolt.

But 9 bolts are harder to find parts for.

If you don't break it, then you don't need parts. Only abuse will break your rear axle componets.

 

I have a spare set of real 9 bolt plates if you're interested. Just PM me and we'll talk.

 

Tell that to the guys suffering with 2.73s.

 

I have an 89 9bolt with pbr and 3.27's. I can't find a drivers side axle shaft to save my a$$. Unless I want to spend 150+ for a new one.

 

Why is he suffering with a 10-bolt 2:73's?????

 

Doc, did you get my PM?

Ed

 

I just decided to buy a NEW 9 bolt with PBR's and 3.70's..
