Be aware that the ACNCM rear bulks alignment for the diff collar is off. It's about 6-8 mm to high and may cause issues if you have an XTM 21 conversion chassis.
I had to mill out the holes down about 8mm. I then filled the hole completely with jb weld, waited for it to set up, then drilled a hole for where the collar needed to be.
Without doing this, the rear center axle actually rubbed on the engine mount screw enough to wear a nice groove in my xtm cvd, and there wasn't any way i could get the engine off without removing the whole rear section first.
Just an FYI.
Other than this, the bulks are damn solid. I beat the living crap out of my truck this weekend for 4 hours and no repercussions.

BTW, see the reversed engineering thread to see where the extra bracket that comes with them goes, scottm was nice enough to post something useful in that thread, even though he did not mean to, thanks again scottm :wedgie:
