For better or worse, I want to upgrade from manual 11" drums to power drums.

Here is a pic of what I ordered from Advance Auto for $118 (after applying a mail order discount). This was supposed to be correct for my '70 Challenger R/T.

The booster looks like the correct one (Bendix) to me, the M/C does not

I know at least the booster should be painted black, but I am not sure about the M/C. Should I paint both the booster and M/C semi-gloss black, or just the booster?
