Title says it all I have a rusty 98 LC. Nothing too serious. I have completed a "rustoration" by removing scale, applying rust bullet, top coating with rustoleum and maintaining with Woolwax on and in the frame. Obviously this does nothing to improve structural integrity to any damage already done. There is one hole in the rear cross member near the passenger rear wheel about the size of a dime but otherwise the frame is intact/solid. That said I'd like to add an aftermarket hitch reciever such as DrawTite 75095 which is designed to tow up to 6000 with a weight distributing hitch. I have two problems (maybe more). First am I even going to be able to safely salvage the holes to bolt this on? Would I just drill out the holes and helicoil them? I imagine with the rust the threads in those holes are shot. Would this be safe? Second suppose I was able to bolt this thing on would it be safe to tow 6000 lbs with said mostly superficially rusty rig? I'm probably crazy for suggesting this...
