Dunno. Have to remember it's a '53 and they are slow, 45mph tops, if still geared the same. Flatheads can be tempermental too, and not very robust. Parts also may become an issue. Fuel pump diaphram kits (not whole pumps), points and condensors, generator parts, oil filter cartriges, open starter drives, voltage regulators and bulbs for the 24v electrical system, if still in military format, can all be fits to find and require era specific knowledge to maintain, repair and operate. It would be a scary proposition for me. If I were looking right now I would stay between 1976 and 1986, look for a CJ8, consider a CJ5 and if nothing else, settle for a CJ7 like I did. 50's stuff is really getting old now.
Paved roads, another example of government waste!
