Look at it this way. I would be all over you like a "Duck on a June bug" if you took ,lets say a restorable 1949 split window bug, slamed the poor thing down on the ground, chopped the top, cramed a turbo 10 carbed 2.5 litre engine in it and wheels wide enough to cover 2 lanes of freeway.
My thoughts on this sort of "doings" if it be a "Louie 14th" table or a collectable VW, Don't do anything that you cannot reverse or put back stock.
With all that said,Its still your coal truck and you can do whatever you want to with it. :lol:
