Thanks again Jerry, I have new hurdle in this project that advice would be appreciated on. Apparently (based off of other posts on other sites) the axle center is a little larger. I don't think it will be a problem with the wheels I have but I will investigate when I can. Should I re-drill the truck brake drums that already have the larger center? Or should I have the center turned down to fit car drums? Still reading on car drums...They are not perfectly dimensionally the same. I think car drums might be 3-4 mm deeper. I am trying to reason out if that would be a problem with backing plate interference or exactly where the overall depth difference is. Advice?
