I think I should switch to the Dana 60 from the 9" that I have (not modified yet), for my build. It looks like my rear frame width will be about 22 inches or maybe even 20. This will put the brackets up on the tapered area instead of the axle tubes, and I don't really like that idea. Besides letting my Chevy buddies talk me into the 9"! lol What are your opinions on this? Are there particular Dana's I need to look for?

About the build:

65 Dart
back half four link (probably) ladder?
14 point cage
500 stroker
RPM's or Victors depending on $$ at the time
727 trans
plan to move firewall back about 3"
possibly move rear axle forward 3" or so
I'm guessing around 2900 lbs or so.
Have 15 x 14 7.5 bk sp. Draglites 32 x 14+ slicks
4.30 gear?

Thanks guys.
