How many O rings on the rear suspension rocker

[stay_upright]

When I took my triangular shock linkage out in the middle (large) bearing it had 2 o rings on one side and 1 on the other.

Also the small bearing had one thin silver 'cap' type washer on one side and none one the other - has some-one been bodging this?
It didn't look as if anyone has touched these since new though I could be wrong. What color is the OE grease - mine is purple.

From Go Fasters as far as I can tell there is 1 o ring per side and maybe the washers on the little bearing there should be 1 each side.

Which brings me onto the question - are there any better detailed drawings for the chassis or even a chassis manual?
