I just mounted one a week ago. I found that 2 of the 3 holes lined up nicely with 2 holes in the crossmember, but the holes were like 1/2 inch big which would have meant a ridiculously large bolt if I were to tap them....so instead I re-used my stock front bumper hardware: I dremel'd 2 of the threaded inserts flat and JB welded them into place in the crossmember as a kind of nut-sert, then used 2 of the T-47 Torx bumper bolts which are kinda low profile. For the frame side I drilled and tapped for two M12 bolts, also re-used bumper bolts. I banged it pretty hard last weekend and it's on there like a champ. I'll see if I can get some pictures to show what I'm talking about because I'm not sure what I just said makes much sense LOL.
