building 8 3/4 489 section

we went D-60 in both our cars when we went trans brake. My old Mirada had a truck D60, and my dads Duster (now mine) we got a S60 from Cass at Dr. Diff. When setting up gears the S60 is sooo nice with side adjusters rather than the shims. That said.... "IF" I was going after a 8.75 (not a good move with a stick imho....) I'd go the new modular piece too.
