Tranny swap question

[84 400]

I have seen some of the posts on this on the site but am looking for some options and ideas. I have a 1984 c10 (in sig for options). I want to do the oppiset of most form members and was wondering what your thoughts were. It has a rebuilt th350 in it now with a shift kit and while it is a nice tranny i am sick of automatics. I want to swap for a 3 or 4 speed. at first i wanted a 3 on the tree but now i think a 3 or 4 or bigger on the floor would be more fun to drive. I need some info on this swap. I know i would need the clutch and brake pedels the tranny maybe a new drive shaft and some mounting brakets cross bars on and on and on. But i am going to be coming into some money and figured i will put most away in the bank or market for retirement. however i think some will have to go into my old truck to make her the way i want. So the biggest thing will be the tranny swap. then an eaten psoi rear end with 373's a 2 or 4 inch cowl induction hood, some wider rear tires, maybe traction bars, new seats ( see my post in "what did you get done" for the seat in there now.) Also a new paint job and a possible super charger are inthe works. As i said it might sound to some like i am dreaming but i finally will have the money to make this happen and the only thing i would not be doing is the paint. Also if i could find a long stepside bed i would consider that but i have never even seen one in person.
Thanks
