I would like the rears if they bolt on to an 86 grand national 8.5" rear withought modification. Do you have pics, Joelzip@lycos.com thank you

im pretty sure you have to weld the caliper bracket on the axel tubes. i could be wrond though.

If they were recently removed from the car, I guess he could have ground them back off the rear end some how...

It is NOT a direct bolt-on for a GN as it is made to fit the earlier A-body and F-body cars without c-clip eliminator axles.

To fit on a GN, an adapter plate is needed, or the existing plate modified.
