Ernie,

They do make unfinned 11" brake drums.
NAPA part # 640-1156.

Are you sittin down.

Figure about $150.00 EACH

NOt an easy itwem to find in the JY either. Most brake drums you find in the JY are pretty much trashed. But, you could get lucky.

Sorry for the bad news. Maybe someone here can get you a better deal. I know I had a difficult time finding them myself.

Good Luck,
Frank
