Thanks Jim, sorry for assuming everyone referred to diecast metal cars as DC. It was a 67 Mustang at Hobby Lobby that I copped at the 40% discount (as shown in the pic).
You actually get two sets, one with a black center, and one set chrome, but be advised that they are very wide. In fact I cut the front rim down and replaced the tire with a set I printed.
To fit them under the rear I had to cut out the rear seat, and modify another chassis to fit them under it.
