Have a look at the highway vehicles regulations before you get too far into the project. Some Canadian provinces have statutes about "fortified" vehicles which are intended to prosecute gangsters who up armour their cars against gunfire from other gangsters. The concern is that the added weight of their hillbilly engineering is too much for the brakes, and thereby constitute a road hazard. You might have an argument with some official who makes a spurious connection between your reconstructionist replica intentions and unspecified ill intent. 'Think of the children, don't you know.'
