FYI, that pick is of the older rear disc setup, not the PBR ones.

I think there are some threads in the archives on this and I *think* you can modify the axle tube flanges on the 9 bolt to accept the PBR brake caliper mounting brackets.... Not sure though...

Look at the pads.... Dead giveaway right there, those are the same pads that the stock non-1LE front brakes use which is what the older rear discs utilized as well..... I would get a hold of the seller at once and verify if that is the pic.....

Yeah, definitely not the PBRs... you got hosed!!!!

FYI, the PBR calipers themselves are aluminum and have fins on them; and they float inside a bracket/carrier thing. The backing plates are much smaller than those in the pic.

Yeah, you almost got screwed there. I've seen a lot of people selling those setups on ebay and saying they're "1LE" and 89-up, which they are not.

If anyone needs to see what the PBRs /1LEs look like, check out my rebuild page here:

This is how a "real" 89 up set up looks like!
"REAL" : cause this is a Baer setup!
A bit higher in price but new and no need to run around hunting for parts .......!

If it's a Baer setup then it's aftermarket, so how can it be a "REAL" 89 up setup?
