Hey 92NSX, I have some also somewhere around here. I bought them thinking I would need them since my drivers side window was moving slowly. I didn't want them to "pop." When I went to install them, we found the problem was already corrected and my window was just misaligned or not greesed enough.
I'll make you the same deal, $10 shipped to ya!!
Let me know
Z
PS - Let me go find them.........
