Well, I don't know what the difference is between my '90 LB and mkbruin's '88 LB, but I just bought the Reese 37042 and there's no way it's going to bolt on (reference earlier posts on pg 1, this thread). Rails on the truck are around 45" apart, and the only way to extend the 37042 that far (very last mounting holes on center piece) is to use the extra side brackets, turned out, as in "side bracket location 4" (pg 3, installation manual) and bolt it to the underside of the rail. None of the holes line up with the one and only hole with a welded-on nut and the other hole, which doesn't have any threads, meaning I'd have to drill, but would have to do so right next to the unthreaded hole (weak) and I'd still only have two bolts holding the whole thing up. Could drill one more hole in the middle, maybe, but that's still two strong points and one weak one, and that last hole on the bracket definitely sits well off and behind the frame rail. Like I said, I don't know what gives, but I'm a little bummed. Price is down to $114 at Wally World, if anyone else wants to try. I'm heading back to town to get my money back.
It looks like this thread is dead but I'm hoping you all can help me out. I've got a '90 LB and I need to get a hitch since the bumper is banged up (PO must have backed into a tree or something). Can anybody comment on how the Reese 37042 or 37152 fit on the '90 LB. The 37042 is $260 and the 37152 is $190 up in Canada so I'm hoping one or the other will fit since they're both available. I don't mind drilling a few holes to make them work as long as I'm not compromising any structural integrity.
