Chainsaw Repair

I bought a great 455 on ebay couple years back. It has been a stand up saw and I have used it every day since. But my chain started getting bone dry so a couple of youtube videos later I think I have it fixed. BUT, lol, I could get my throttle cable off to look at something else without taking the handle apart. Today I was putting it back together and the white nylon piece on the end of mine broke. So I am looking at buying another. I need to know what the difference is between a 455 and a 455e. On ebay I found this http://www.ebay.com/itm/Husqvarna-Throttle-Rod-537260801-537260802-455-Rancher-460-chainsaw-/130630521353?hash=item1e6a2f9209:g:TuEAAOSwWxNYnI5i and it looks like mine. But I would rather go with this http://poweredbymoyer.com/genuine-husqvarna-537260802-throttle-rod-455-rancher-460-461-455e-oem/ , but the picture is crappy and I cannot see if the white nylon part is on the end. I want to know the difference to insure I am getting the right one. Restocking fees are a beatch.

Thanks
