New cast iron rear drums
I ordered new rear cast iron drums and the drum bolts with the longer shoulder for swaging. The shoulder (swaging part) of the bolts is just short of going thru the hub and drum. Turns out the drums were not champfered to give the bolt shoulder room to expand when swaged. I had to take a large drill and champfer all the bolt holes in the drums. I contacted the vendor about this and they denied any problem with their rear drums.
The front drums were okay. If ordering rear cast iron drums you may have to modify them slightly on your drill press.
