Update: I removed the axle and found that both end had been smashed slightly, likely from pounding the axle in/out with a non-rubber mallet. A little Dremel clean-up and the pins slide right in.
I would like to take this opportunity the mention how awesome Pit Bull is. Their products will out last any bike, and they have great customer service. I ordered the pins Thursday and had them on my doorstep Saturday.
I would also like to thank Riders Discount. I normally order everything through them, but they recommended going straight to PB, since I needed them faster than they might be able to get them to me. Excellent service as usual.
