Technical Trekking rear shock absorbers?

[Liteboy]

When I was under the car doing the exhaust I noticed the rear offside shock absorber body was badly rusted, so looks like a pair of shocks for the rear are going to be added to my list.

Has anyone changed theirs and if so any recommendations? Was going to go for Spax as I have used them a few times before with good results but they don’t do a replacement, the could do me a custom set but suspect they would be

Check shop4parts.co.uk (this Forum's favourite Fiat parts specialist)... There are a few variants for the 4x4 shocks (depending on engine and trim), but likely the Trekking is the same as the rest of the rear suspension is identical -- they just left out the rear drive

Keeps that salt-laden mud from eating its way through the non-galvanised parts (on any car...)
