dumb wheel question

[mrt2you]

i did a search but couldn't find anything.
i have a chance to buy some hub centric wheel spacers really cheap i want to know if they will work on my mustang. they have 66.1 mm center hubs.
i am no where near my extra wheels or axles to measure them so i ask here.
my question is what is the diameter of the stock wheel center hub or what is the diameter of the axl

Nope, won't work. You'll need 70.5 mm for the Mustang.
