1974 BBP A-body 8-1/4" 3.23:1 sure-grip rear axle
Man, that sucks!
I can assure you, this is the original rear axle out of my Duster 360 4-speed and it is 100% an 8-1/4" axle.
I just picked up a 1973 Duster last night, so I thought of pulling this axle off the market, however I have another 1974 8-1/4" unit that I just built with a brand new clutch type Trac_Lok differential, disc brakes, and 3.55:1 gears so I do not need the keep them both.
Have no fear, I'll get photos none the less. I will need them for my library anyways.
