VS gold and black stripe

Does anyone know where to source the gold-black-gold stripe for a red and black VS?
Thanks!

Hi Folks - I've been calling around and now got some recommendations of firms that may be able to make one. I'll let you know how it goes, Phil

Ok folks, so I went to several auto signwriters and took a nice sunny drive to Worcester with my rolled up sheets of pencilled greaseproof paper.
In the end I bottled it (opted to save the stripe), replacing the lower half panels from behind both doors all the way round the back & blending the paint in below the stripe. Luckily I managed to refit everything removed & get the car MOT'd before I crooked my back, so a summer waxoyl session awaits when I can crawl around under it again ...

Well done, probably better to keep it original. Sounds like to did a good job
