Converting rear drum brakes from SBP to BBP

rrvolare said

Wondering ,,,,, is it possible just to change axles to BBP and then install 10 inch bbp drums on rear ?... Keeping the same backing plates ..shoes and wheel cylinders ?.
Is there a p/n drum BBP that will work with SBP original shoes and backing plates ?
thanks

No, there isnt. The large bolt pattern drums have a larger center register and dont come in the narrow width you'd need.
Just swap out the entire rear brake assemblies. Ditch those tiny shoes.
Your already going to replace the axles so why not replace the brake backing plates, etc. with 10x2-1/2"?
Very little cost difference over what your thinking of, if it was even do-able.
