Hi Chris, my extensions came from NTS, and the track rod ends are the same ones I've had all along - the ones on the donor were knackered and I had to angle grind one of them off the upright!
I've still got my dodgy lock stops on the rack, so clearance is fine
I've rumours that Nathan has redesigned the top wishbones to improve clearance, but haven't seen any evidence of it yet (it might have been Johno that mentioned it to me).
Didn't Nathan put a post up the other day to say he'd switched his phone and email off for a while to avoid distractions and concentrate on clearing the backlog of work he has?
