4-speed conversion

74Duster, you didn't come out and say you had one already, but Sherman & Associates makes a fabulous four speed conversion panel. When I bought mine, it was only $99 and the quality's outstanding. (I have everything needed to convert my Fastback over except for the guts to cut a bigger hole in the floor of my rust free Spring Special LOL ... so I'm content with a reverse manual for now.) Here's a link if you want to check them out.

Best of luck with the project!
