the steering box on the outside of the frame will give less turning radius to the right because the front wheel hits the box. bigger tire diameter means less radius because the bigger tire hits the box sooner. another issue is getting it done without bump steer, which makes for a scary and (can be) dangerous ride. a lot of guys use the toyota box that goes in the same place as the stock box and looks a lot like the stock conversion kits sold by the vendors. really, a lot of builders think the conversion os waaay to much money but then when you look at the other trinkets on their project that cost the same or more you wonder why they thought that when they had no problem spending money on other things that are peripheral systems and not a safety system that would be considered the basics. my thoughts would be spend your money on a good foundation, steering, brakes, suspension, tires, etc. then you will have a good, safe unit. after that the rest can be purchased as the budget allows. its like building a house and not building a proper foundation because it costs too much and you really want to save that money for other stuff like cool flooring or windows or something.
just my thoughts, its your truck and your money so you gotta do what you want.
