Cool project, keep up the good work. I've always had a soft spot for '70s trucks myself.
Most recent one I owned (below) was a '76 SWB/BB/NP 435 4speed. (not an original BB truck though) Those are cop wheels with redline hub caps. I lowered it but nothing dramatic - just cheapo rear shackles. It mostly just leveled the rake. I never got around to doing anything in the front.
I drove it all the time and on some pretty long trips too. One day it wouldn't start and left me stranded pretty far from home. After that it ended up sitting in my yard for a couple years. Parts of it were starting to get rusty and leaving it outside uncovered wasn't helping. Didn't have any interest in fixing it up and I sold it as a roller. It was a cool truck though.
