I'm getting ready to order drums and talk to the machine shop.
I want to look at the 2067DGS later model 4WD drum and the '74 Wagoneer drum.
After more studying and measuring, I found there is one measurement that is crucial. The distance from the inside face of the drum that contacts the axle flange to the outer edge of the friction surface cannot be less than 3 1/16".
If anyone wants to measure the 2067DGS they have for that measurement, it would save me a little time and trouble. If anyone is running that drum and that measurement is less than 3 1/16", I suspect the shoe is hanging out the back of the drum some.
