That's why engineers invented shims. :wink:

Did you measure the existing bushes or the frame?

I've just stripped the shock out of the frame.

Top bush as supplied is 22mm, frame is 22.3mm.
Bottom bush is 46.9mm, pivot plates are 47mm

For simplicity I'd use the off the shelf parts and shim to suit

Washers in the hardware setup = more parts to wear (and more fiddly too!)

I measured frame.

Shims/washers will be clamped in position = no wear.
The existing bushes have no evidence of wear on the mating faces, that means the bush does not move.

Do you have the original bushes?

I have been under the impression that the bush is the bits that sits in the shock (between shock and 'reducer')?
And i call the 'reducers' hardware?

I'm an engineer by trade (geek with machine tools :lol: ).
Hardware (to me) is nuts, bolts, washers, shims.
Bushes are the parts that go between hardware and (in this instance) frame and shock and are usually of a softer material, in this case aluminium.

I can take pics of the bits I'd like you to measure if you like.

And i call bushes the bit that sits in the shock (the sacrificial bit, normally plastics like nylon etc.)
