I've read on this forum that window guides from the Fiero store are not any good. I purchased a set and am in the process of putting in new side glass. If these are not good how can they be made better?

I have the same question, I've got a brand new passenger side window ready to go in and a set of FS guides. Look forward to any suggestions/tips.

I've got a brand new drivers side and am waiting for some help. To use or not to use, that would be my question. There must be a way to make them acceptable though.
