Re: 70 GMC Disc/5 Lug Conversion

The measurement is from Wheel Mount Surface to WMS. Not the back of the brake backing plate. Different brakes can have different depths and contours. The WMS to WMS will always work.

I got some cheap angle iron stuff from the hardware store. Get the kind with lots of hole ans slots all ready in to. Bolt a piece to each drum and use a tape measure between.
