Help ID 3 broken/missing parts on a 041-AV saw

[ADK_XJ]

Hey all, need some help troubleshooting a couple of parts on the old Stihl 041 AV Farm Boss I bought this fall. I already hit up arborist site but this seems like a good group for the older saws.

Here they are (with pictures!):

• I'm missing a "bushing" between the bottom part of the top handle and the left-side of the body (first image), anyone know the proper name for this piece as I already tried ordering a "annular buffer" but instead got the two part piece that goes around the rear handle (second image)

• Am I'm missing something on/in my chain tensioner setup on the front of the saw (third image) - it was quite loaded with sawdust and gunk but, even after cleaning out, I can't find a slot for a screwdriver or hex or Allen or anything - what gives?!

• Finally, I found this broken off piece of plastic on the lower part of the right, front end of the body (fourth image) - right by the underside of the chain. It's attached by a flat head screw and washer but looks like there was more to this at one point - any ideas?

Thanks to the experts in advance - saw runs great but would really love it to be tip top before my next use.

Do you have the saw's illustrated parts list (IPL)?

I do not but now I'll go look for that.

Google/search: STIHL 041AV IPL

I see more than one site has a free PDF file of the IPL for downloading.

Yeah, so I found that and found that the bushing I'm looking for is ALSO called an annular buffer without any designation for it being on the front handle rather than the rear.

Still trying to figure out what's up with my chain tensioner however - I know where/what it is but I'm not sure why I can't see a screw thread or hex?

Got some great info from my duplicate thread over at Arboristsite and figured I'd share it here if anyone happens to be searching:

#1 - I confirmed from an illustrated parts list / spare parts list that the top/front bushing mount I've been looking for is this one: http://www.ebay.com/itm/NOS-OEM-Sti...254?pt=LH_DefaultDomain_0&hash=item1e95e32916

#2 - Looks like I was looking at the wrong piece for the chain tensioner, it's actually lower and to the left

#3 - And, last, that off-white plastic piece off the bottom is my slightly chewed up chain catcher and not some broken piece of a larger part.
