315x60x15's on my 64 Dart GT

When I had the rear narrowed and had to relocated the spring perches,I got advise from Crackedback to set my pinion angle at -4 then weld on the perches.This weekend I snapped strap bolts and a strap,so when I get my new spool/chunk back I,ll be using U-bolts for holding the u-joints now.Will be drilling out the yoke holes for the bigger U-bolts.

Cool Rob knows his chitttt! I was gunna recommend you talk with him!

I tried once to drill out for bigger bolts etc on the car, that flippin metal is VERY hard. Try to have it done before it all goes together. You WILL need a drill press for sure! On my new chunk I have the U Bolts on it 7290 U Joints.
