I searched around for the 5/16 chrome hole plugs and found out that only the ones at Menards fit correctly. I bought all I could find at two Menards and only have enough to do one and a half wheel! I need 56 total which sucks because they 1.09 each. I have to wait for more to come in. As far as center caps, I am going to have a set of stock center caps sprayed black when I have the spoiler and grille painted. I attempted to paint the lincoln emblems a color other than black and silver but it is impossible to make it look good. They are too small and my hand shakes like I am going through heroin withdrawl when I try to paint them. Lol. I will just put the black ones on from my wheels. The one picture is after I stripped the paint off the little emblems. Impossible to paint!
