So one of the bolts that hold the tail light to the rear fender -part number 90162-292-000 - is messed up. I think the bolt threads as well as the nut on the fender have damage. I want to run a tap and die through them, but don’t know the thread size. How can I find this out? I don’t have the tools to try sizes. I checked various parts outlets and manuals, but to no avail. Thanks for any suggestions.
