Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Thanks to Joe Jump for encouraging me to go into more detail with the differences in the shift levers. Also thanks to Craig Sheldrick for sending me information about the dog leg differences via e-mail.
For the loop frames, Moto Guzzi used footboard shift levers which attached to the associated linkage via bent rod held in place with a cotter pin. Later models (V1000 I-Convert, V1000 G5, etc) had a solid 6 mm shaft welded to the shift pedal and the associated linkage was held in place with a circlip. Within the shift levers, it seems there were at least a couple of different varieties. Some were straight while others had dog leg bends in them.
