Downsides were 1/2" wheel studs, narrower track width and of course smaller axle shafts.

You say your axle is from an HD pickup? Could it be an AAM 11.5 even? I'm real savvy on the visual differences. Either way, nice score!
Those measurements are all good news to me. I never noticed the difference between the front and rear, I suspect because of the way the rear fenders somehow masked it.
It is a AAM but it does have the 10.5 ring and the removable pinion support. I think I read somewhere that the 11.5 version does not have the removable support.
I just realized that I think I misunderstood Steve on the differences in pinion length in that the 60 is about 1 1/2" longer than the 14B that I have. Oh well, Ive got a good driveshaft builder not too far away in San Jose.
