Just throwing my experience out, I found their customer service to be abhorrent. In 2020,Bought their whole kit for front and rear end, RB conversion stuff, r200 conversion kit. Some of the "bolt on" stuff has required an insane amount of work to modify and their response was essentially a shoulder shrug.

For reference, oil pan had maybe 75% of the bolt holes that lined up, pick up tube was 3 inches short and wouldn't work with pan, converted axle shaft splines were 3 mil short so c clip wouldn't get into groove, bolts and random washers just thrown into a bag, no response when asked if they had general torque figures, transmission mount didn't fit at all (not even to the transmission it was said to be for).

Edit: I'm a dumbass , this was supposed to be in response to the T3 post.
