Hey Fred, Jason told me about the upgrade, very cool, your car is an inspiration, I took a bunch of pics of it at the Wedding in the rain and had it as wallpaper forever.
good luck on the search- I (along with a bunch of other people here) would recommend Tyler at ATS for the swap kit.
I would be concerned about shifter location because your car is so clean
I got my 6 speed from LS1TECH.COM
good luck-Chris
