Small bolt to big bolt pattern

Jason Smith said
What is the cheapest/easiest/smartest fix to convert my sons 5x4 small bolt pattern to something else that gives him more of a choice in wheels?

easiest way is to try and find adapters that bolt onto the hubs, kind of like spacers, problem is, they magnify the problem.

best way, upgrade to 73-76 Disc brakes up front and order new axles from Dr Diff for the rear.
