If that link is not helpful for that vendor (sometimes when images are magnified, the ends are left pixel-ated etc.) LMK.....
I think I have an extra set of the 'SHO' letters that Classic Cars Ken made for my interior doors left over.
They're black vinyl, and the edges maybe possibly be crisper than the images found online.
They may BORROW them for this project as long as they're returned (I recall Ken saying he was going to stop making the hood stripes and those letters, so I need to keep them on hand in event of an accident, etc. **cringe**).
LMK If needed, I can start searching them if so.
