I agree SKIPPY, but I have a 12-bolt on the rear. which does provide nice ground clearance. but isn't a floater, and is a bit on the weak side
the D44 front, i'm not so worried about (but if I found one, I would run it for sure)
and I already have matching gears for a 60 that a member here gave me for free. for $100.00 for a diff, another $100 for a spool...... and for essentially $200 I upgraded my rear (minus driveshaft changes of course, and brake lines etc.)
