young and need help

There is this thing, I can't remember what it is called, but you can bolt it up to your wheel studs and use it to measure backspace and tire and wheel clearance so you get the right fitment the first time. Blast, if I could only remember what its called.

Btw, stockton wheels make widened mopar steelies. Just not sure how much they run, never have emailed them for a quote. Maybe someone will chime in who has experience with stockton wheels
