Shift Kit

Which is why it's a big debate for me.
How hards the TF-2 to install, I've been looking into it and apparantly the supplied directions are a bit iffy. Doesn't seem that hard as long as you keep the parts clean and in order.
Can't find one of those gaskets for a 904, only for 727's.
Edit: I should explain that I can't do the work at home so I use an open source shop near me so I have to drive there, do the work and drive home so I don't want to get stuck over there lol
