Thanks Jess.
I did find these decal stickers on eBay but they are described as 60mm in diameter with doulble back tape. 60 mm = 2.36 inches.
They look very similar but I'm concerned that they may not fill the original center caps fully. Close but not the 2.5 in diameter required.
Sketchy shipping response time also coming from South Korea
Opinions?
