Accepted Original Colours These are the shades that JSM can supply that may be suitable interpretations of the original colours supplied on the production line. Original colours are often widely disputed & debated - and we do not want to limit your choices or be too pedantic - so, where possible, we like to offer a few options. For more in-depth information about original colours for particular models, please contact us directly to discuss. Note that the number of shade options may increase/decrease depending on the availability of shades in that particular material (i.e. Grained vs Smooth Leather or Nylon vs Wool Carpet shade options may differ).

Designed as a convenient option for quickly covering the interior of the car – either completely, or leaving half open so you can still drive the car – Tonneau Covers became a staple item for many sports cars of this era. Following on from some quite radical changes to the bodywork shape of the Giovanni Michelotti redesigned Triumph TR4 models – the accompanying Tonneau Covers were also updated to suit. Despite very obvious changes in shape to suit the new chassis design – the overall concept of the Tonneau was the same – with a pocket located on the drivers side to allow the steering wheel to be covered when the cover is fully in use – and the slightly off-centre zipper offering a larger opening on the drivers side for when using the cover half-open – painting a very nostalgic feel to a Sunday morning drive on a crisp autumnal day in the Cotswolds! A tab was sewn to the underside of the tonneau cover for securing to the fixing located on the inside edge of the passenger side seat base framework. This design was maintained for the proceeding TR4A, TR5 and TR250 models – with only changes to the fixings used to attach it to the bodywork being updated. The TR4 models used Lift-A-Dot fixings, whereas the TR4A, TR5 and TR250 cars used the “hood” press studs; the TR4A versions in silver, whereas the TR5/250 were originally in black (plastic).

The majority of Triumph TRs left the factory with PVC Hooding – this is effectively a pvc vinyl plastic material with a waterproof membrane, and featuring a grain in the surface of the material to imitate vinyl/leather. The actual material used was Everflex (known as “British Everflex”) – which was an ICI trade name for PVC Hooding (think “sticky tape” and “sellotape”!). Some special-order models may have left with Deluxe Mohair Canvas. The TR4 to TR6 Tonneau Covers all seem to have been available in either White, possibly Off-White, or Black Everflex from the factory production line.

Here at John Skinners, we have patterns and templates for all the different Triumph TR Tonneau Covers. These have all been templated using the factory designs and donor cars – of which John has owned a few himself. This cover is supplied with the pre-sewn steering wheel pocket located on the Drivers Side – as well as the zipper located off-centre depending on LHD or RHD cars. The underside located “wind” securing tab is also included. Note that these same patterns and manufacturing processes have all been used consistently for 40 years – to good effect with our kits winning many awards the world over. However, please be under no illusions – the Weather Equipment elements (Soft Top Hood and Tonneau Covers) are tricky to fit, even for an experienced trimmer. We strongly urge you and your professional trimmer to contact us for directions on the best methods for fitting these items, as some fitment processes are irreversible. These parts are not meant to be easy to fit – that’s why when they are done correctly, the material is as tightly pulled and tort as a drum. Remember that a well-made kit still requires skill and attention to detail in order to fit it successfully, but a badly made kit will never yield good results. Don’t leave this to chance – use a John Skinner kits, and ensure you fully understand the process of fitting before you start.

We can offer these kits in the original PVC “Everflex” Hooding, or in the more premium Deluxe Mohair Canvas material, in a variety of colours to suit both the “as original” enthusiasts, or those after a more custom finish to their restoration.

You may wish to consider our Convertible Soft Top Hood and Hood Frame Envelope Cover to complete the external “Weather Equipment” set.

To briefly summarise the details…

As of January 2021, the UK is no longer part of the European Union (EU). As a result, several changes have been implemented which affects how EU based customers now purchase things from the UK. Here is a brief overview…

The UK Value Added Tax (VAT @ 20%) is no longer applicable to any customers purchasing from outside the UK, assuming these goods leave the UK. To clarify, no VAT (20%) will be charged on initial purchase for any goods leaving the UK.

Instead your local country tax is charged upon importation into that country. This is based on the value of the goods as stated on the customs Invoice we supply. For most European countries – the result of this change is minimal as most local taxes range between 17% and 22% for the large majority of EU based countries. Note that some countries have lower tax rates, and others have higher, this is purely a guideline.

You will be contacted by a customs official upon arrival of the parcels to the destination country – and they will request payment of these taxes.

All shipping agents levy a small administration charge for “clearing customs” normally of a value around €5 – €10.

Our products are 100% UK Manufactured, therefore our products are Tariff/Duty free – meaning that you should not incur additional tariff charges upon importation. It should be noted that we use the HS Commodity Code (Tariff Code) 8708.99.9790 “Parts and accessories of the motor vehicles of headings 8701 to 8708 > Other Parts…” – for the majority of the kits that we supply.

For any Trade or Wholesale Customers – if you provide us with your EORI number – then this is noted at the point of import, allowing you to claim back the Tax from your local government when you issue you tax returns.
