nope not off hand i dont. the gpz rear wheel i just aquired is an 18x2.15....same as the 78 comstar that was on my 750f. i currently running the 16x3 off the 82 kz750....sprocket carrier looks like it might fit the 18, but i havent pulled the rear wheel to check the fit. brake rotor will swap over if i drill some holes for 5 bolt pattern. found a couple of websites that carry the same part number for the drive hub assembly, and one that sez they are different numbers. i got all winter till spring to figure it out.
