looking 4 hub caps?

[Ricks1971]

Hey guys I put a set of 2006 chevy take off wheels on 1972 3/4 ton pick-up. I had to get the right lug nuts to make them work. The fronts look great but the rear axle hubs stick out too far to use the hub caps. I found out that a 2005-06 1 ton duelly truck comes with the same hub cap and its deeper and should work. thought maybe someone out there might know where I could get these hub caps. Thanks Rick
p.s. here's a pick of the wheels
