welcome to the garage Steve, always nice to see more TF series here
the swap is possible, either way, but not simple - the 58-9 frames are a
couple inches longer at the front because of the different splash pan and fender shape of the later years, and the difference in the way the hood hinges mount means the holes in the firewall are slightly out of position for the other style, either way .... otherwise it can be done, but don't be suprised if you have fitment headaches
