You own a Sawzall or a grinder and some cut off wheels? That's all the money/effort I'd put into a B2 for fitting bigger meats, especially if it's just a cheap-hold you over beater. We fit 33's on a buddy's just cutting and hammering, cut the roof off truck style and beat/jumped the ever living piss out of it till it siezed (you would be surprised how long they run with no water in them). Mike is right about side windows, and that's a lot of glass to clean up when they do break, part of why we cut the roof off that beater to begin with.
I have a buddy that does actually wheel a B2, he's got 6 inches of lift and 33's. The guy that built it already had one lifted ranger, so he just copied all the brackets on his own then bought lift coils for it.
