Supplier of parts for medium and heavy Historic Military Vehicles.

Located on the Surrey/Sussex border, close to Crawley & Gatwick Airport. 10 minutes from M23.

We are proud to announce the formation of Green Barn Parts Ltd. This is a new independent sister company of the existing WW2 heavy truck restoration business, Green Barn Services.

Green Barn Parts is a new UK-based parts business specialising in NOS, new, refurbished & take-off parts for GMC, DUKW and larger WW2 trucks including Ward laFrance, Diamond T’s, Autocar etc., as well as a smaller number of parts for Halftracks and armoured vehicles. Our team has over 75 years’ combined experience in private and professional restoration & preservation of a wide variety of Historic Military Vehicles.


We are also pleased to announce that Green Barn Parts is taking over the complete stock of GMC and DUKW parts from the highly-respected Rex Ward Automotive. We will be continuing to supply all of the high quality parts for which he has been known, along with a large number of new lines.

This means that Green Barn Parts will be the UK’s largest GMC parts supplier and world’s largest DUKW parts supplier.

We have been working closely with Rex for the last few months and we hope to continue to do so as we develop our new business. For the time being he will continue to provide his hydrovac and GMC water pump rebuild services on our behalf, but we anticipate moving this in-house once we are fully established.

We are working hard to list the vast majority of our stock on our website. Anyone who has seen Rex’s stores will appreciate the scale of this task, so in the meantime if you cannot find the item you are looking for please contact us and we will try to help.

We can be contacted via the ‘Contact Us’ page; by phone, SMS or Whatsapp on +44 (0)7983 292506; or on Messenger via our Facebook page @GreenBarnParts. The website offers online payment via a number of secure options, and we can also take card payment over the phone or in person. UK shipping for larger items is via Parcelforce 48hr. International shipping is via Parcelforce International.


We are located near Crawley, approx. 10mins from Gatwick Airport. We are happy to receive visitors but we politely request that this is by appointment only please.

Green Barn Parts will also gradually become the sole supplier of Green Barn Services’ range of replacement parts, repair panels and upgrade kits including:

  • Proven upgrade parts such as electric fuel pump kits, halogen headlight conversions, alternator conversions, discreet indicator systems & more.

  • Cab & body repair parts & replacement panels for GMC and others.

  • Diesel engine conversion parts & kits for a variety of vehicles.
