NOOOO... That exerts a twisting force on the rear cross member. It WILL warp it and twist the hell out of it with any good hard yank.
Use the existing holes in the rear cross member to install a pintle hook. It will bolt right on, that's whjat the holkes are spaced for. It is preferable to reinforce the crossmember with at least a quarter inch plate on the back side. I also put a 2x2/3 by about a foot long gusset behind the crossmember. Located laterally, right between the upper and lower bolt holes.
THsi should handle most snatch runs that you will ever subject the rig to. I prefer to also add a rear bumper of 3x4 sqautre tube with a 3/16 wall section. Sleeve it where the bolts for the puntle go through and tie it to the longetudinal fraem rails too. Other wise it is still possible to pucker/bow the centerof the rear crossmemebr outward with repeated vigorous snatch runs.
Be sure to beef it up. When I bought my 40, it had (still has) this great big piece of angle welded on the back with the hitch welded to it. Looks like crap. When I was working underneath I notice that the rear cross member was bent really bad! I'll bet the PO tried to "jerk" something and it bent, then he welded the angle on to fix it....
