Shawn, you would have no issues mounting a 60 box on your 40. It's basically straight inboard of the front of the front tire, on the outside of the frame.
Minitruck is WAY easier BTW...
Does your block have the holes tapped for the FJ60 power steering pump? IIRC yours is a '77 so it will be like mine, which doesn't have those holes. So you would probably want to go with something like this...
Or at least get the pump bracket from them and use a Saginaw pump (which is what I did)...
