A while back I picked up an 8.25 axle with posi and 4.56 gears, complete drum to drum.
I'm still trying to decide if I really want to run this thing. I've heard so many people say 8-3/4 is the only way to go, but they're so hard to find for an A body. This thing will never run tons of power or anything more than street tires most likely, I'm pretty sure it will be ok since it was used without issue in a fairly serious Duster drag car before I got it.
Anyway, if I do use this I want to make sure I have everything lined up and ready to go. I'd like to do the inboard spring kit at the same time. So, please add to my list if I'm missing anything:
BBP wheels
U-bolts (where to order?) the holes on the 7-1/4 shock plates?
Driveshaft (are U-joints different between 7-1/4 and 8-1/4?)
Assuming chassis to axle brake hose is the same?
Offset shackle/hangers (Mopar or Dr Diff?)
Gears...I'm going with 3.55 most likely. Any helpful links on swapping gears in this axle? I may attempt to do this myself if it's not too bad.
