Funny this would be mentioned about the 67-68 tachs. My 68 Bird had an original 68 short style tach. Then when I bought the one to put on the LeMans, I ordered the correct 67 tall style. At first, I could NOT get used to it at all. I almost ordered a 68 style. However, after a few months have past, I have completely reversed myself and now I like the 67 taller tach much better!
