Hey JNCers! I picked up my 3rd Datsun last fall to join the 521 and the 1959 l210!
(I am not sure what happened to my 1959 L210 thread, but I am guessing it died when the forum got its cosmetic changes? I will try to make another sometime.)
This 510 will be my daily beater, as it has a good-to-go LZ22 under the hood. But is a tad cosmetically challenged with its spraybombed cammo paint job! Which is kinda neat, with the hidden bre stripes, but not quite my thing.
This bitchin dime was built by Chris of Maine of the BBlist. He named it Chapman, and true to the spirit wanted to make the lightest 510 he could, so it is missing a ton or the interior.
A very New England 510 with its FUTOFAB and New England SCAA stickers in teh window.
Currently I am scrubbing off the paint to get down to the original paint/patina beneath! On to the pics.

The other thing I LOVE about this dime is the custom military style dash!

There is no interior to speak of but I did get some stock 510 seats from Chris!
Let the paint removal begin!
And a little snowman on the hood from my Daughter.
All in all this is a really straight car for New England. But eventually I will have to do something about the fiberglassed rear QPs.
Since this shot I have removed the cammo from the hood and grill and bumper. It is a long process! Eventually it might see a paintjob. But I am a fan of patina Datsuns, and don't want to lose teh mojo for a while. But knowing me, some bitchin door graphics will show up soon enough and who knows what other cosmetic touches. Some of my inspiration!
