Re: Two Piece Front Hub/Drum Assembly

[Matt Haas <mhaas@xxxxxxx>]

A lot of the front drums were held on by the wheel studs. If you look at 
them closely, you'll see that the splined part of the wheel studs comes 
through the drum slightly which serves the same purpose as riveting the 
parts together. AMC solved the drum falling of the rear if you lose a tire 
problem with three small screws that hold the drum on. GM tended to use a 
small clip to do the same thing.
