Oh, I didn't mean to match it with a car, just in general among our discussion that the S/N's vs. dates seem to follow. If his S/N was, let's say, higher than mine for his TH400 date then maybe that would lead us to believe it may not be a '67.
But......here is what I do see, specks of black paint on his tag. Wasn't the tag on a '67 TH400 for an L35 black vs. following years?
