In what order should i do everything?

i have everything that i need to do all of the necessary stuff on my dart.

including the front end rebuild kit, new tci transmission, new hedman headers, new pypes complete exhaust system , and new rear end with new leaf springs.

in what order do you guys think i should start putting everything together?
i've been debating back and fourth on what order to do everything.

for my headers, i am going to need to take apart part of the suspension anyways, and maybe with the old headers out of the way, the transmission install might be easier.

i'm just confusing myself trying to think of what order to do the stuff in.

any suggeestions help..
