Gas Tank Needed

[dumbfarmboy]

I have a brand new behind the seat gas tank and sending unit that I need to swap out for an under bed tank. Anyone have any interest? If not and you have an under bed tank for sale let me know....Painted all of the fenders and getting th cab ready to finish and paint this weekend. Front end done and also ready to mount the motor and tranny.
As I think about putting this back together, it seems to me that I should put the motor and tranny in as well as the drive shaft an then mount the cab and build the font end back from that...am I nuts or is this the right way to proceed? First time EVER doing an off frame and frankly it still scares the crap out of me that I wont get it put back together right. Also anyone have any ideas for wiring harness?
