Was watching the 550 for seal removal video posted in the how-to section, and the oil seal circlip used was a straight circle with the two ends you need the circlip pliers for, like this.

Can I use a modern circlip like this instead? My honda dealer can't get the old ones anymore.

I also wanted to clean up the front end a bit, and not use the fork gaiters (plus mine are all cracked and worn). Obviously I still need to protect the oil seal, so I wanted to use a regular dust seal. I talked to my parts guy, and he said that not all 35mm dust seals would fit, as it needs to also match the OD of the fork tube. Does anyone know what bike I can use the dust seal from?
I found the 51425-375-003 part number by searching (fits later 550s, 750s, etc), but those are huge and ugly.
