Hi Kevin, you of course need the wheel itself, the appropriate center cap for your application, a reproduction rim blow switch, a ground wire and a Black plastic spoke end cover and screw for the front of the bottom spoke where the switch ends are located.

There are 3 center caps, The one shown is for Plymouth in 1971, another 1970 version is identical but has a Barracuda emblem in the middle and then there is Dodge version without the 3 fake allen head bolts but with a metal band on the front face of the Black rubber that has the word "DODGE" stamped in it twice.
