Tranny Rebuild Help 904

Thanks for all the help guys. Here are the two things I'm planning on getting. I want this tranny to be better than new. Any other weird seals I need? Also, I have the cheap Hooker headers on the 318. Is it going to be a huge pain in the *** to get the tranny out with them on? Because I refuse to put them on again, they are coming off with a saw. Or can they stay on there? If not then I'm pulling out the checkbook for the TTIs.

What is a "rear band"?
And anything else I should be getting?

Thanks for the help!
