Replace your old, beat up, original disc brake backing plates with this superior quality reproduction. If you are doing a points judged car you will need the part numbers stamped just as original or face a points deduction. 

Correct silver plating with correct stamped part numbers. RH and LH pair. For use with original 4 piston disc brake calipers. Officially Licensed GM Restoration Parts.

Equivalent to GM Part numbers 1381722 RH, 1381723 LH

Note for single disc brake conversions use W-383 or W-383A

NOTE: Cad Plating is an immersion process and parts coming out of this chemical bath may have slight "runs" or "streaks". This is normal and should not be considered a defect.
