10" Rear Brake Problem

Crewchief....I'm in the same boat as you. I bought an A body 8 3/4 that the seller claimed was out of a '68 Barracuda. I pulled the drums and it looks just like yours....no auto-adjusters. I'm also missing the metal bar just below the wheel cylinder that has the unusual spring on one end (I don't know what it's called). Did you ever get it figured out??
