The most common sheet metal problem on the Minor is rusted floor panels. The floor has numerous spots where water can get in and eventually rust the floor. The original floor is all one piece and would be extremely difficult to replace that way. The solution is the grid system. Floor pans have been produced to allow individual replacement of each side of the front or rear floor. These panels are designed to be replacements, not cover-ups; simply cut out the old floor and weld in the new. Extra metal is provided for overlap seams if desired.
