These are NOS Stanley fork reflectors for SL70 K0, CT70 K0, Z50 K1-K2, and many of the early model Hondas. Some of these may include SL90, CT90, CL90, SL100, CL100, CB100, C70M, Passport, C102, CA100 and C100. Check with your local Honda dealer to ensure application before bidding. The stud is .50 (12mm) for SL70. The stud will need to be filed by .125 (3mm) for ct70 and additional .125 (3mm) for Z50. These are not in the original packing. They were in a large box of nos parts purchased from a dealer that went out of business.
