I'm sure you know the work it takes to convert A/T to M/T. Most people that I know use the 555 trans, M/T, it handles quite a bit of power w/o too much work. If I was you I'd get the Turbo Mini Van and put a M/T in it and have a whole alot fun and plenty of room for kiddo(s). I was going to do that but I already had an old 68 station wagon that I decided was more fun.
