re: aluminum brake drums

Hugh:  Do these ones from AutoZone come with the iron inserts as well?  The
price of 70.00 each seems good.
 
I can probably pick up some 240Z drums off a neighborhood junker.
Presuming they are still thick enough to re-surface, I wonder what the cost
of re-surfacing and machining them to fit a TR6 would compare with this new
price.  I understand the holes need to be enlarged and some material taken
off the back.  Not sure of exact specs for this.
