I am restoring a 1962 C105T. I don't like the solo seat and want to go to a longer one. I presume I will have to make a rear mount. My question is are the CT70 and CT90 seats the same width? I have no seat to compare them with. The front bracket on the tank appears to be similar.
I think the CT70 set has more overhang on the side and isn't really that long., plus is mounts differently. I think you'd be better off using a CT90 buddy seat (pad) which attaches to the rack, or a C102 "cub" type seat, which is the long one piece unit.
