Hi Terry is incorrect , most unusuall.
I failed miserably to obtain a Hinge Pin for either end of the cap in USA so go to your favourite fastener shop and get a Stainless Steel Rivet that fits with a mushroom head and cut to length +1/8". Drill the end out so as it can be fitted with a 1/8" ball bearing and push it in position .
This will splay the dead end open.
Get a SS washer and place behind the splayed area.(IE The area opposite the mushroom head)
I do have a almost new cap though!! NOT FOR SALE Chuckle Chuckle!!
But I shall personally fly over there next Friday 20th and ambush any Honda dealer to get me a pair of pins. Ashevill NC next Saturday look out.
But I will buy any NOS or OEM pins.So will Terry.
Cheers
Dave in Australia.
