I'd like to upgrade to 18" wheels, but they don't make these with a 5x4.75" pattern in 18x10"

However, you can buy an 18x10 with a 7.27" backspacing. I could use a 4.5" to 4.75" 1" thick adapter to get my backspacing correct for a 10" wheel on the rear.

Has anyone used these adapters before to run Ford bolt pattern rims?
