There is no reason to diss the example on eBay, but it is far from "stock". Way far. I love the "museum stock" reference. Can't wait for some museum to step up and offer me the big bucks - ha! We museum stock guys talk about things in terms of correct, correcter, and correctest. And it is a tough nit-picky conversation! Vicky provides a great illustration - the Japanese oil filter would be correctest. Stock is defined by the ZCCA to exclude just about any modification or aftermarket part. This definition drifts into the "all original" conversation. For my cars, even Nissan / Datsun replacement parts could be different (many times they are) and not correct for the year. Thats why we are seeing huge money being spent on fabric covered hoses and such. Kats just found a correct alternator for his car - very small difference, but what he had was not correctest. The 7 / 70 date could go either way. If the car was sold in July, it was a '70. If it was sold in August, it was a '71. That's why I could care less about "model years". It was built in '70 - it's a '70.
