8 1/4 rear question

Wizard said
Did they have 8 1/4 rears in dusters? for a 318 or did they still use 7 1/4 stock for 318 and slant 6?

I'm pretty sure they made it in the quarters for the later model years of a body's. Those other questions concerning whether they had a 318 or slant 6 you'll have to wait for somebody else to chime in who knows more...
