----- Original Message ----- Historical note: 1955 was the last year that Chrysler used lug bolts that threaded into the brake drums. There are locating pins on each axle flange to help align the wheel before threading in the lug bolts. That's what the little holes between the larger lug bolt holes are for. The driver's side lugs were left-hand thread- apparently to reduce the tendency of the spinning and vibrating wheel to loosen the threaded fasteners. I never did buy that one. In 1956, Chrysler began pressing the lug bolts into the brake drums (axle flanges?) and using lug nuts to hold the wheel to the drum.

Not sure when the practice was finally given up, but 58 is the last year I have had experience with.
