ok...
#1, i dont particuarly care about "legality" here in indiana. they dont even look at the car or care about it when you plate it. that being said, mail people drive around in RHD cars, and i have driven one before, its not that bad.
#2, for the sunroof hole, i thought about patching it with sheet metal but i dont think im good enough yet to do it without warping it, so i think im going to cut it a top off another car, im not sure how much of the sheet metal ill use, ill be generous in cutting it off the other car though
#3 yeah, the welds are very globby, but they have been gone over like 3 times, the first welds just looked really bad, i think they fully penetrated though, then i welded over them again just to make them look better. also, im still going to add a 45* angled piece in both the front and rear adding strength to it. THEN im going to have a 10 point cage installed.. it should be a very strong chasis when im done.
