Cmayna, That hubcap looks just like mine and I used decals I got from Jim Carter (stock DE104). They were less than $2 for each cap. I haven't had any trouble with them staying on except a couple letters peeled up a little and I dabbed a drop of weatherstrip adhesive behind it and it looks good, just not painted like the original.
Here's a pic of the hubcap on my spare(if I can get the link to work). Pete
