How are year one 10" brake Drums?

I wish I could find one with grooves, because other don't fit all the way over the log bolt stud & the holes just mash out more over time! So what brand might would have that!... yell I was hoping yearone would have ones that have groove holes & Mopar symbol stamped on it wear they have other stuff that looks like stock, but don't seem that way!

From your picture the grooves you are talking about is where the drum & studs were swedged together. They don't make them with the grooves. Read here and see picture on post 14
