My b4.2's showed up today and they are 90% done in a little over 4 hours (10yr old didnt help much I installed gear diffs instead of the ball diffs and the tranny is really tight to turn by hand, my SC10's are easy. Is it just because they are new do ya think? The actual diff is smooth but when I try to spin the spur its very firm to turn.

And AE forgot to thread one of my rear axles so now I wait again. My SC10.2's are conversions and I havent changed them to cvd's yet so no spares.
