Depends on how much of the original D50/MM you want to throw away and replace with different parts... The only thing stock on mine is about 60% of the sheet metal/body

Mine sits on a 70's Dodge Frame, with an Altered 114" Wheelbase, Narrowtrack Jeep D44 Front Axle / Chrysler 8.25" Rear (Eventually swapping them for a pair of Dana 60's) and 6" of Lift (4" Suspension, 2" Body), and Trimmed Fenders with 40" Tires.
