S-10 10 bolt backing plate size and pattern

[mikesplumbing]

Anybody know what fits the rear axel backing plate bolt pattern for my 1999 S-10 10 bolt. I have a brand new 67 chevelle drum kit (Police intercepter drums) still in the box. They are for a 10 bolt but i'm not sure if the backing platepattern is the same between models.

Thanks
Mike

To find if parts will interchange I go to an online autoparts website and look up the different parts numbers

Found the answer, the only difference is the center hole needs to be opened up on a lathe to fit the larger axel boss. The four mounting holes on the backing plate are the same.....
