Well, truthfully I was going to do it the same way you did it, but my main reason was kinda bunk. I didn't want to alter the wheel well. Which now when it gets around to it, id way rather modify a fender flare to fit than doing all sorts of patch work. So it worked out that both tubs were twisted up pretty good.
Fighting bad sheetmetal is tough unless your last name is Hendrix
I went the route I did to avoid messing with the flares !
Unfortunately I do not have a welder, but mainly the problem is I don't have sufficient power to weld anything anyway. But yes, It is going over to my body shop buddy tonight, and maybe in a week or so it will be ready to come back and I can fit it to the frame and figure out where everything will go. Then the tub part will go off for paint, and the frame will go out to be built.
I have seen a few people use an extension cord to the dryer to get power for their welder . I cant imagine how much I would have in mine if I paid for the labor , but a professionals labor would be much quicker .
Haven't decided if I am going to run a pintle hook or regular ball setup. I am kinda leaning ball simply for universal reasons.
I looked at both of those , and ended up going with a GSPUP/Ruger trailers hitch . It is simple and quiet . JScherbs TSC coupler is also a neat design that is fairly easy to build yourself .
My thought WAS to box in the front part of the tub, however, I think I might do a CJ syle drop down tailgate - that way If I want to toss an axle in it or something I'd have some room to do so. Mainly for time reasons, but also money, I think I am just going to run those low tread 33's on the gambler wheels until I feel like coming off the bones to get Kevlars.
On the front tailgate opening I plan on using a bolt in plate to add some rigidity to the front of the tub . The local machine shop is breaking it for me out of some 1/8" steel . I thought about the double tailgate , but the cooler and spare tire mount up front will block it anyways . One last thing to think about is the floor panels arent the strongest , so loading an axle would probably beat the floors up pretty good .
