How to tell if trans cutout for 4spd is authentic

[Keith Tedford]

In the later seventies the 4 speed hole was cut out with a torch. Our Chevelles look the same. There was a copper guide laid on the floor pan to guide the torch. It sure looked home done so it shouldn't be too hard to duplicate. How you are going to spot weld the shifter box on over the hole could be a problem if you are looking for the original look.
