So I have either had a brain fart, don't have a clue what I am doing, or something else.

I am rebuilding a power shift valve body of a maroon 7060, and for the life of me, I cannot figure out where these two parts go.  The small spring, and the small collar.  They came out of the valve body this I am sure, but it is almost like they fell out of somewhere, because I meticulously lay out each part as I take it out, and I don't remember where these came from.  I do not see them in the parts book, I do not see them in the service manual.  I kinda think maybe the collar is someones attempt at a shim for pressure, but the spring has me confused.  I have rebuilt these before, and I don't remember seeing them in those.  I will say that the sleeve was missing from the inching spool, but the snap ring was there.  Just baffled, so I will swallow some pride, and ask you the experts where are these from please.

Been doing some more digging, and I think these are part of the missing inching valve components.  So the newer style is a sleeve with a nut, and I know the older style is a snap ring, but was the sleeve more of this type of collar, and was there an extra spring, that went between the collar, and in the inside of the inching valve plunger?  I have a newer manual, and I pretty much always use the AGCO website which is also going to be the newest drawings, and part numbers.  I think I need to dig out the older manuals, that doesn't have the newer style inching valve shown.
