I'm buying a ford 9" rear end for my firebird, and the manufacturers only option to fit this housing for f body disc breaks is 93-02. I can get calipers, discs, pads, lines but no parts store nor gm dealers can order the mounting brackets. Any clues, besides rummaging through salvage yard, on where I can find a set?

 

this site has a classified ad section.i bought mine off craigslist.theres always someone parting out a forth gen.btw i believe the 93-97s use the same rear brakes as the 89-92.

 

89-97 are almost the same, some small changes but they pretty much all interchange.

I did this back in the early 90s, not hard at all. Good luck with your swap.

 

TTop, this isn't a break question but since you've already done a 9" rear end swap, what's difference in 28 & 31 spline axels? I'm gonna be mostly street, and the strip just once in awhile.

 

3.

If you can get the 31 spline, I don't think there is a cost difference so a little extra strength with the 31s are good.

 

31 it is, thank you sir

 

I ordered a Ford 9 inch 31 spline rear end today, can't wait to get it installed.
I've had to do a lot of searching online and also calling auto parts stores and GM dealers for the information I needed. So I figured I would list a few parts that I've gotten, in case someone else with a third GEN is wanting to upgrade their car. Hopefully this will save them some time on gathering info if they come across this threat.

I also have a full ls1 front and rear brake setup for sale, I have the rear backing plates as well, they aren't perfectly new. PM if your wanting to buy the backing plates. I can get some pics for you
