need brake backing plates for new bb axle swap

If the center register on the new axles is the same as the register on the old axles, all you would need to do is drill your old drums for BBP and use your current brakes. Plan on finding backing plates, brake parts, and drums from '65 up B, C, or ANY '73 or newer rear wheel drive Mopar with 10 or 11 inch brakes. If you want discs look under mid '90s Jeep Grand Cherokees... Oh,, and welcome aboard, don't be shy with questions....
