Nubs on Cop Wheels

The wheel pictured below that you call a Magnum GT was also used on B-vans I have seen many I remember having a set and was frustrated because I couldn't run the bottle caps with out the nubs, there not as scarce as you think, another center that looks good that I will be running on my police wheels on my 56 Dodge truck is a called a " spider cap" very common on hot rods they are sort of bullet shaped then have smaller cones covering the lug nuts, just google spider cap under images you should see them, they are available in most hot road and wheel shops
