Wheels

[skysoldier173rd]

I picked up a set of old school aluminum slots off EBAY. They have the large center holes and the appropriate lug spacing, no problem one would think and that is true with the back wheels, but not the front. The drums have a little pin sticking through the front in 3 spots. The flange on the back of the wheels is of course flat. The old steel wheels seem to have a recess to accommodate the pin sticking through. I'm calling it a pin but really don't know what it is or it's purpose. Wondering if I can just grind it down to allow the flange to seat flat against the drum which is what is needed. Tell me what you think and thanks. The white arrow shows one of the pins. Surely some of you have ran into this.
