Really limited by only your fabrication abilities...
I'm Putting a late 80's-mid 90's kingpin Ford Dana 60 (driver side drop) in Spring Under Configuration up front...
1988 Ford Sterling Rear out back... with a disc brake conversion
Cummins 5.9L Turbodiesel, Ford ZF S542 5 Speed OD manual, Ford married NP205 (driver side drop)
power steering, hydroboosted brakes, 4 wheel disc brakes, and readily available parts for engine, transmission, clutch, transfercase, wheels, tires, brakes, bearings etc all "in-stock" at my local part house vs. trying to find the golden goose of parts.
Mine will also be an on-road tow/haul pig and occasional firewood adventures into the woods
