Thanks to all of the responses!
Tom: The vinyl looks good. I have not tried fitting them yet, because I don't want to disassemble the ones I have. The main reason I want original cores is because Gerrit says the seam fits into the groove in top of the cores to keep the seam straight. I have not seen a core without the vinyl yet to be able to discuss how this works out. If Gerrit says it will, I believe it.
Gary: If you had a non-ac pattern from bwalvoord, I'm sure you could duplicate them.
Richard:
It would make more sense for me to go ahead and remove the vinyl from the ones I have before spending that much for shipping plus the cores?!!? Thanks!
I will look at mine tomorrow, decide the best option, and get back to y'all.
