"B" Body 8 3/4" in a '65 Valiant

I just scored a bare '69 "B" housing for $40.

Now comes the hard part.

After moving the perch location inward 1/2" a side, I have to find brakes, axles & a center section.

Right now my biggest concern is finding all the proper brake parts.

Everything else is relatively simple from a technical stand point. Any suggestions? What would a good price be for the 10 x 2 1/2" backing plates W/all the mechanical parts less drums?

Also, does anyone know the proper size offset/backset for the stock "A" body wheel?

I'll need to add about 1 1/4" of offset to get back to the normal track.
