1995 E-150 Club Wagon Chateau package here. No problem getting mechanical parts...body, interior, vehicle specific, yes challenging. It sits around mostly as my tow rig now, probably won't replace it.
The hard part for me is dealing with the advancements in engine technology and transmission (gearing) seems to be light years past where we were/are. Your 7.5L/460 has 245HP and 410 ft/lbs torque. Today's smaller 6.2L has 385HP and 430 ft/lbs torque. On top of that the new 6-speed trans does a fantastic job of getting that new power to the ground.
