How many bumper strips / slides is my saw supposed to have??

[Colty Bolty]

I am working on getting an old 009L running to use around the house... I'm wondering how many 1121 648 6600 Bumper Strips are supposed to be on this saw? I have one but it appears there are possibly 2/3 more spots that im unsure of. I will try and attach a few pictures

Thanks!

Calls out 2 but only shows 1

IPL shows 3, the ones you've identified. It's unusual to see one in the clutch cover, but then it is a Stihl...
