Due to our products being hand made in nature, some of our product dimensions will have a +/- 20mm tolerance during manufacture. Please be aware of this as there is a slight chance that it may impact fitment on ex-military and/or historical vehicles. Our patterns are legacy documents, some of which are over 30 years old and conform to the original artefact for which it was designed. We cannot guarantee that our canopies, trailer covers, or other such material conforming products will maintain a “perfect fit” on your vehicle due to, but not limited to the following; potential after market modifications performed by the ADF on vehicles during service, general wear and tear of the vehicle over an extended period of time and potential modifications performed by private owners over the life of the vehicle. We please ask you to bear this in mind prior to purchasing as to align your expectations of our products when fitting to your vehicle.
