I picked up this 521 last year locally off of craigslist. Had been sitting in someones back yard for a while....didn't run and some of the brakes were locked up. I've been into Datsuns/Nissans for years and when I saw this I just had to have it. Since then I've got it running pretty well, put disc brakes all around, aluminum Fiero radiator, hardbody bench seat, lowered 2 inches, and put on a set of newer chevy truck 17" steel wheels. It's a neat little truck.....haven't seen any others in town yet. I'll try to update after I make more progress with it.
A few before pics.....
And how it looks now...
