here are some pictures of the lenght of the shifter. I am posting them cause I look everywhere and could'nt find them anywhere and I might help somebody and I know for a fact that tech 2 won't share that info
extension of 3.250" according to a person who bought the shifter from tech 2
here is mines done by me also

here is mines closed with marling crawling forged first gear thrust washer and bearring carrier installed also everything done by me
if you want to buy the 1jz bellhousing buy it from champion toyota in texas they sell it for $300 plus shipping is way cheaper than driftmotion and tech 2 . here is the phone # 1-713-943-7010 ask for Jeff , he will hook you up
hope this help......................Omar
