Re: [AMC-List] BW M12 tran question



Back in the 70's when I lived in California, I installed a FMX tranny in
our "Were Gone" 12-second street-strip 69 SC/Rambler. It has been so many
years since I did it that I have forgotten exactly what we had to do to
install it but the FMX held up to the abuse we gave it!
