Any specs on how much needs to be machined from a small nut bus drum?
My bus is running Beetle brakes on the '68 Tranny.... Im currently running Thing drums but wanted to put on the Machined bus drums to tuck my back end in a little. Got a set that look nice, but they bottom out on the backingplate when you tighten the nut.
I think the lip on the back needs shaved down.
