68 Barracuda Convertible 452 cu.in. 4-speed

Michael, yes you need to use the cap of the AR wheel. Maybe you find someone who can use the not needed Ralley style chrome pieces. On the attached foto you can see the detail how to connect the original center cap base to the mopar dog dish. You need to open the original cap, weld in (in my case) 4 connection pieces and then use some kind of a polyurethan based cement to attach them to the cap. Any more questions please let me know.
