As you can see, I've elected to arrange by engine displacement, then by years produced (keying by the first year.) I may re-arrange this table into a "matrix" for easier reference, but that requires more coding and formatting - and I just haven't gotten there yet. It would be the same information - just a finer sort, and (probably) a "busier" chart.
Of course, I've got more references than I can post here - if you're still having trouble, drop me a line. I check the WiP email several times a day, and I should be able to get back to you within about 36 hours (even if that answer is just "I've got to look some more...")
