I had a hell of a time setting up USA standard gears in a 8.5 10 bolt one time at work. The pinion depth was all over the place. Took like 4 or 5 hours to set that rear up. Then when I talked to my parts guy he said hes has bad feedback on those gears and apparently they are richmond rejects and known to be noisy.
.
No idea on the noisy issue yet. But the setups went quite well in the 14bff and d60 I just helped on. Nice patterns and good backlash readings.
I'd buy them.
I didn't set these up personally, I had the 10/12bolt diff polished and blueprinted by a pro corvette diff guy...Richmond 3.90's with 12 bolt spiders and cross shaft, and 31 spline Tom's Kickass axles.
