This is the 1970 521 that my son and I bought together. He is posting about it on reddit/r/datsun and I am posting about it here.
As you can see from the pictures it is in fair condition for an east coast truck. We ran an compression test this weekend and you can see the results on my other post.
We are hoping to get it up and running by the summer or 2015 but time and money will tell.
You can see some of the extra parts that I got with it in the bed. A hood, tailgate, new bumper, valance under front bumper, new grill, new package shelf, 4 headlight and buckets and bright rings, Hitachi & Weber carburetors, stock air cleaner, fuel pump, tons of small NOS parts nuts and bolts and badges, 5 new hubcaps, 3 sets of bumperetts, instrument cluster, original keys and and a bunch of other stuff I have forgotten. Oh, and a clear title too.
We paid $500.00 for the lot.
I will keep this thread posted as things progress.
