O.K. basically I have no clue here

The ones on the car were stamped halibrand and I thought they were aluminum. I received an email from Kris kinkaid for a set at 800.00 ouch!. The wheels are trigos so I guess Kirkham thought the original spinners would be a nice touch. I am open to suggestions. I have seen spinners with marks on them and flat spots maybe i am just being too fussy here with mine. They did take a bit of a beating though. I would like some good advice here
