HI, i am taking the cab off my 1949 chevy truck and i'm in the process of taking the wiring and gauges out. The problem i am having with the gauges is that the oil pressure and temp gauge are hooked up to the engine and both sides are rusted on. i can not get them of even with leverage. any tips? Also when i do get the free and loose how is the end going to fit through the cab? Would it be easier to cut them and buy a whole new gauge? Also what is the best way to take the wiring harness out of a truck; from inside out or vise versa. If you could explain how you might have did it, i would be extremely thankful because all the wires are driving me nuts! thanks in advance. Mike
