walk right into your local ford dealer and go to the parts counter and ask for the chrome center caps for a lincoln mark VIII chrome 10 spoke directional wheel. the ford dealer across the street from my shop has them in stock, 14 bucks each.
you decided to buy a money pit mark VIII, and you say damn that sucks? 14 bucks each, thats the only time you'll ever see a part for these cars for 14 bucks, and thats brand new, so if money is tight you got the wrong car my friend lol.
