Watts linkage spare parts

[red astra]

Hi there, 

I have an astra 1.6 j 2013 with Watts linkage on the rear suspension. Found 1 of the bushes slightly worn. Don't know if I can obtain a bush or the full rod. Tried e

bay and all the usual sites (don't want to go to dealers if poss due to excess price). 

Can anybody tell me if bushes available or if a complete rod. Can anybody tell me a source where I can obtain said part. Many thanks in advance

You could try using poly bushes from somewhere like DemonTweeks who sell PowerFlex bushes and may have a listing for what you're after
