[Dwight Varnes <mxbreed@lancnews.infi.net>]

Anyone able to help with the following pre-owned type parts?

Rt rear caliper and mounting bracket 
Lt rear hub and brake rotor
Brake proportioning valve under car at rear

Would also consider a complete axle if close to central Penna.
Thanks, need these to complete an axle.
