This one is 70mm and the Honda is 68mm. You could grind some off.
Also have to check the thread pitch as I just took a guess, but they have the other pitches.
OOPPPPS that didn't work. But they do got them.
Side note: I don't like Hondapartswarehouse. I ordered something from them about two years ago and weeks and weeks later I finally called them because my parts didn't show. Idiot tells me they only had two and I ordered four so do I still want them ?? Stupid chimp to stupid to give me a call. They were real quick to take the money off my card but not quick to give me a call. I don't like them.
EDIT: Forgot to add that I almost never got my money back from Hondapartswarehouse. They kept stalling. Went through two reps and a manager to get my money. Each time there was a long delay and no money on my statement. Finally had to call the credit card company to reverse bill them. Credit card company scolded me for not acting sooner. They said there is a time limit for them to reverse bill. Deal with those clowns at your own risk.
