Condition of this synchro.

Opinions please . Can this be re-used or are both parts too far gone?

 

It looks like the brass has worn away and the race it sits against is discoloured too. This is part of the 1st/2nd stack on my 020 box

 

I suppose the surest way to know is to measure and see if they are within tolerance. The other consideration is, how much are new ones.

 

How far down onto the cone does it sit?
