Mancini Driveshaft

Just waiting on a shipping quote to see if it's feesable.

Little confusion though after looking in my Mopar catalog and Mancini's site. On a 741 case how many splines does the pinion have? I want to replace the yoke with the style that takes u-bolts rather then straps.

Also contemplating keeping my 7260 joints and having the shaft retubed and saving some cash but I jsut don;t like those straps

Mancini sells the u-joint girdles too, just drill out your existing yoke. It works on the same principle as the u-bolts.
