Reproduced for the first time ever, this lower boot strip for your VC Valiant is copied exactly from the original and is available only from this website, and our listing for this item on eBay.
This top-quality item has been duplicated to within 0.01mm of the dimensions of the original extrusion and manufactured by an automotive OEM.
Note that this is not the boot seal (which we can also supply) but the strip that goes above the rear bumper on the inside of the boot opening as per the photo.
The strip is held on by tabs on the body of the car (careful, they can be sharp), but if they are rusted off like they were on my VC, the strip can be attached with contact adhesive, double-sided tape or windscreen sealant.
