I run an 8.75 behind a BB stroker with manual trans in a corner application. It has held up fine with 200 TW tires in HSAX which is standing start. If I switched to sticky 50 TW track tires I would probably break it on the standing start.
I think the D 60 would be good if ratios work for you. I would use the taper bearings or double taper non adjustable Ford style bearings. Not green bearings.
If the D60 ratios do not work, a beefed 9" is an option.
In my case I run (and need) 3.23 so I don't think a Dana 60 would work,
I like the Dr Diff 11.7" rear discs which should work with any of the axle choices.
