This is what my Mom's fiancee hitch install looks like, I told him to get one off a truck instead of a blazer. You can guess which one he got. He has 5 grade 6 bolts on each side of the rails holding it, and he welded the hitch to the original bumper brackets. Now that he can't use the truck bumper hes going to make a bumper out of c channel. I'm no fabricator by all means but I bet I could do a better job. He claims that he's a certified professional welder and could get a job anytime.
