Hi mate. Volkszone can throw up some odd bits sometimes otherwise patience and ebay. I've had a parcel shelf and a few other bits. Have seen a few rear panels in the past but not many headrests. They usually come with seats attached. Even the shows do not seem to have much second hand T4 stuff yet. I'll keep my eyes peeled.
Yip patience is a virtue im afraid T4's parts are like gold dust still so few come up for sale just keep checking Ebay or Ebay.de as Germany seems to have lots of secondhand parts avaialble
