I just bought a 1990 Firebird Formula and for some reason the driver side has a Edelbrock valve cover and the passenger side is stock. I need to pull them to replace the gaskets as they are leaking and would like them to match. So, if anyone has a pair (or is willing to sell just the passenger side cover, please PM. Thanks!!!

I've been looking for a pair of those for a long time. They don't pop up very often.
