I ordered a F-15 touring windshield for my '91 Honda CB750 Nighthawk. It is supposed to fit but doesn't. There is probably a half inch gap on both sides of the headlight housing. You would have to go to a hardware store to get a stack of washers to fill that space so it will tighten up. Also the bolts that mount in the bracket so the windshield can move forward and backwards we're not long enough and would not fit. The most frustrating part is when i inquired about returning it, there was no offer to make it right or find a windshield that would work and also i had to pay $20 to ship something back that obviously didn't fit. so essentially i paid $40 to have it shipped and then ship it back and received no product.
