Thanks y'all! I had been originally using a bat, but was having similar problems with the jumping or rattling when coning. I'll look into a fancy bat. At this point it's more about the fact that I can't get them out, and I want to be able to get them out. I will not admit defeat!!
I'll try some penetrating/soaking lube and after that sets, some heat as well.
I'm pretty sure Alpine no longer exists as a company -- this wheel was made several decades ago, or so it would seem.
And no, there are no wingnuts under the pins. I'm not THAT much of a plebe, folks
