You are bidding on one set of four (4) 1/24 scale drum brake backing plates, cast in white or tan resin, as pictured. Included are two front and two rear backing plates, for four total pieces.  Minimal prep work is required before finishing-- usually just a final soapy water wash, followed by a clean water rinse to ensure any dust is fully removed and the surface is completely clean.

Backing plate measurements:

Outside diameter, both front and rear: ~.540"

Total thickness (excluding axle flange on rear plates), front and rear: ~.170"
