Apologies for posting to a suuuper old thread, but thought I'd update it with some info that I've found when buying some stripes for my Escort.
So, the guys at Yesterford (
link) stock these in the full kit but can also do just the stripes if that's what you're after. Check the link for 'Body Transfer Kits'.
Both are reproductions so you
shouldn't have problems with them like you would from old kit with stale adhesives, faded colour, etc.
