Moog lower control shaft pic needed.

[vanceman]

I recently purchased a set of " Moog " lower control shaft kits from o'reilly's. On one of them the caps would not thread on to the shaft so I took it back. My replacement showed up today and it looks totally different. So my question is what should the shaft look like. The first two were almost stainless looking while the replacement looked cast. If anyone has a pic I would love to see it. I looked on there website and the first set of shafts I got look like the "Rare Parts" shaft, is it possible they are selling lesser quality parts in Moog parts boxes?
