A bit of a challenge to install but worth it in my opinion. It took a bit of work to install them into the holes on my 1976 Honda CB750F rear tail piece as the rubber part that goes through the hole is slightly wider than stock rubber ones but I was still able to install them on my cb750 rear tail piece using some dish soap and needle nose pliers. The rubber is all brand new and they make my cb750 look more complete. 🙂 Over all this is a good product and I am happy with it. I really like how the rubber material feels brand new and it is not hard as a rock like the old used ones that we've all seen. I'm also thankful that this vender was able to sell this product overseas to the US and was willing to use paypal as payment. Also fyi, the export fee for me was $50 on top of the regular price so keep it in mind if that still makes it worth purchasing for you. For me, it's yes because there's no other place in the world that sells these to the US as I've already checked everywhere online.
