I rebuilt my eBay purchased 4x4 and shimmed the diffs using shims from some B4 gear diffs. It's got an RS Pro and a X12 8.5t in for now to see how it does just for a laugh.
I've put lighter fluids in the shocks so I can experiment with swapping them on to my FT.
Be interested to see how long the massively worn diffs last. If chucked a load of shock limiters on and I'm gluing up some stock tyres as they seem to work so well on our track.
All good fun.
