like this;

Best source of badges is eBay - try this link - I have bought some of mine here and the prices are pretty good.

Anyhoo donor badges for my "CARLTON" boot badge. All Vauxhall.




This one is good for front side wing "CD" or boot lid "CDI"
and they make this -------------

Gotta be trimmed, sealed and fitted of course.
When chosing badges from eBay, make sure of the height of the lettering and script style before you buy. The ones I have used are 17mm in height but were advertised as 20mm which also exist. Advice is contact seller and get him to check before you bid or do a Buy Now.
