A body 8 3/4 questions

OK all, I working on putting an 8 3/4 from a B body into an A Body. Since I have the bango, axles and all, I really don't want to spend MORE money on another A body one. So here are my questions.

Since I am shortening it: What is the width of the A Body axle? I know the track width, perch width, etc but not the axle width and a solid measuring point.

Who is a good axle outfit: Right now I am looking at DutchBro's in Portland since I am on the west coast.

Please give me your thoughts on this issue -
