Will this work with an 8 1/4?

I'll answer that question (I'm his dad). He ended up buying an 8-3/4" and I am going through it right now while he is off to college - go figure. This rear end is a 741 case with 2.94 gear set from a '67 B-body (and no brake hardware).

We plan on replacing axle bearings and seals, and still need to round up some brake hardware. From what crackedback said, it looks like we will be swapping stuff over from the 7-1/4".
