vaccum lines and such, huh? I can't help you there, I work mainly with the older smog-exempt Datsuns. Most of that stuff ends up in the trash in my garage.
What engine does that pick-up have?
I used to have a 72 521 pick-up with a stock L16, I put a weber 32/36 DGV on it, it sounded like a chainsaw!
Another idea, look into 510 and Z-car clubs local to you. Most Datsun guys I've met aren't picky, they like all Datsuns and many are willing and able to help.
Drive a Datsun......then decide.
