need brake backing plates for new bb axle swap

I have a pair of 10" backing plates with 10" x 2 1/2" brake shoes and all the hardware, parking brake cables along with LBP drums. All came off of an early 70s B body 8 3/4 rear. I also have with this package a set of new brake shoes and new wheel cylinders. Let me know if this can help.
