Dana 60 Help

Around here it was easy to find someone with jigs who can cut down a Ford 9" but not a Dana 60. Its just something to consider.

Easy here to find someone to cut down a 9" which makes thing simple.
I'm trying to stay Mopar all the way but after looking at the cost of Dana parts here it may be my only option.

WHATS THE STANDARD DIFF MESSUREMENT FROM FLANG TO FLANG ON A 73 A BODY?
