So long time reader, first time poster..... Just got an 85 gt to try out the mod swap. All of the harnesses from an 01 gt and a 98 mark viii motor. Really like the fox body and the older interior and going to see if I can make it all work without putting in a new dash. And if all goes well, I have a turbo kit for it as well. Any suggestions on what transmission automatic-wise would be the best? looking at 3:73 gears.
