12MM_X_8_5/8" 8.5" / 220mm NOT COUNTING HEAD 12MM DIAMETER FITS : CT70 K4 TO 1979 (FRONT) CT70 1980 TO 1982 (FRONT AND REAR) CT90 1977 TO 1979 (REAR) (WITH 43D NUT FITS CT90K1 TO K5 REAR) Hey, I wanted to let you know that the axel bolt bolt that I previously bought (12MM_X_8_5/8") works great on my rear axel CT90 K5 (1974). Not enough threads for the castle nut, nor is there the hole for the cotter pin, but the self-locking nut you sell works great. I would list that in your product description. Thanks! I love the "one-stop-shopping" for my restoration parts.
