Hey Njsurf, just now saw your message, sorry for the delay in getting back to you. I love my '99 Amtran. No complaints whatsoever. I don't have 6th gear unlocked but would jump at the chance to have it done. From what I've read here though it's not easy. So jump at the chance if you can.
Nothing quirky about mine at all. I have the front engine (FE). Are you getting a FE too? One good thing is the ceiling and side panels are screwed in so much easier to take out not having to deal with a 1000 rivets
. Do you have a page setup here yet?
