just picked up a NOS flywheel cover for a CT70. I believe ther are three versions starting with one for the earliest vins that is one piece and comes from the z50 then the two piece then a one piece. I have the following NOS ones that i thought were the same and were from the Z50 but they are actually different. One has black lettering and made in Japan letters and spacing are different. Thinking no black lettering one piece is from Z50 (earliest). The two piece follows in sequence. How about the one with black letter. CT70, Z50 ???
