SSBC rear disc brake help!!!

I installed them over 10 years ago and had no problem. You might contact Summit or Jegs to see if they still have inventory. They both show some SSBC items in their on-line catalogs. Also, I'm sure that those calipers are not custom-made. Betting that they can be cross-referenced to some make/model production car (could be Mustang?).

I know the calipers and pads are the same used on the 87-88 Thunderbird turbo.

Do you remember how yours were mounted on? Both calipers to the rear? Or is one in the rear and one mounted towards the front of the rotor?
