10" backing plates???

Guys, I have a nice set of the 10" backing plates that had the 10x 1 3/4 shoes on them. They came with my 8 3/4 rear, small bolt pattern axle setup. Im thinking of going large bolt pattern on the rear axles by getting a set of the yukon axles they make. Now, if I go with this, can I use the 10" backing plates still? Or do I need different plates? Im hoping I can keep the same 10" backing plates (one less part to hunt down) so if I can, what application do I use when telling my parts guy I need brake parts with the big bolt pattern stuff (drums, shoes, springs, adjusters, etcc) Thanks.....
