O-ring size

[Walkie Talkie]

I need to replace the o-rings on the fork caps for my '92 FLH, the local HD dealerships doesn't have any in stock. Does anyone happen to know the size of o-ring I need or have a part number I can look up with google. I do remember it being item #17 in the parts breakdown for the forks.

Thanks for any help
