I've got a pair of keizer wheel centers and one 6" and one 7" inner rim half for sale. The centers have steel lug inserts. I'm pretty sure these came from a radical. The centers could be redrilled for a different pattern.
The centers have a 2.5" thru hole, and the lug holes are .600 thru lug inserts. The bolt pattern is 4 on 4.5"
Different bolt patterns could be drilled very easily. These are the spun plate type centers, not castings.
100 plus shipping.
Additionally, I have some new never used 3" polished outers, and 4 more centers that use the fiat pattern, 3.850 center to center, .500 diameter lug holes. 40 each for the centers, 55 each for the rim halves.
Can send pics.
If interested, send me a note to ted47dsr at sbcglobal dot net
