Cast iron or steel drum?? Help!

[Useless]

I'm trying to order three right front wheel studs for my '63 Valiant, everyone seems to have them, but they have two types listed. One for a cast iron drum, and another for a steel encased drum......what's the deal here? Can anyone tell me how to tell what I've got?

Thanks for the help!

look at your drum, if the mounting face where the wheel mounts is thin around 1/8" or so then you have steel encased drums. its what i have on my 64 dart.

I had steel lined 10's on my '65 S and Dorman had the correct stud as I went to the more common R hand thread for Aluminum rims.
