Hi Martin,
My 40 has 60 series running gear and I've found that Euro 4x4 are excellent for mechanical parts.The parts are good quality and the service is superb.
Let me give you an example: Recently needed to sort my handbrake out and thought that new adjusters in the drums would make the job easier. The adjusters arrived next day complete with all the clips and springs in the kit to complete the service. I thought I was just getting new adjusters.
Regards,
