Lets just pretend like I actually have the money to do a swap.

3x what baddad said...took the words out of my mouth. Figure your costs and double them. If you can't afford it, don't even think about it. There is so much shit you are going to break and that isnt going to work. I actually broke my arm doing mine...broke a crescent wrench at insane manual torques at a beautiful time(yeah I know, shouldnt be putting much force on chinese crap) and my wrist smacked something...i dont even remember now...and thats a cost i hadnt planned on incurring....
It won't be quick or pretty...but itll be an experience. And until you get the engine and tranny bolted up... a driveshaft will be the least of your worries...
have fun and be careful out there.
