Repair Procedure: There are two calipers listed for the above platforms, FRC11237 and FRC11237A.

Caliper FRC11237 will fit most platforms with the long wheel base or with extended cab.
The bracket of the FRC11237 can be easily identified with a protruding
tab as compared to the FRC11237A where the tab is even with the bracket.
One other detail is the distance between the mounting holes
and the slider pin, the distance of FRC11237 is 3 inches as compared to
the dimensions of the bracket supplied with FRC11237A, the distance is
