I'm going to replace the Neutral Switch in my 1977 GL1000 over the winter but it looks like I should replace O-ring for it as well. The original Part Number 91306-371-013 isn't available from most Honda places. I can find it as "cheap" as under $6 on ebay and other places to much higher at others. Is there a good source for this or do I bite the bullet and order one on eBay or go to a Napa place and start measuring a whole bunch of o-rings? Are there any parts stores that stock Metric sizes for o-rings?
By the way I was on Partzilla yesterday and any part has free shipping for 12/2 and 12/3/19
