I love the whole "GM parts bin" concept. So, I'm putting an L67 in a cavalier, not a Fiero this time, and I stumbled upon something that I wanted to share to the community.
Any 2000-2002 cavalier/sunfire, which is the same one that has the F23 with the correct bellhousing for the 3800, has a PCM that is the same externally as the 98-02 3800 PCM, And it's mounted in the passenger fender-well, so it actually ends up being a really nice bracket, IMO, for swappers that want to mount the PCM outside of the interior. Not only is it encased in a metal shield, inside that is a plastic frame with firm rubber to absorb any bad shock. Further out, they wrapped rubber mat around the computer itself for more protection.
The only problem is it's held onto the frame by rivets, so you'd have to drill them out or something at a yard.
But here are pictures of mine. Please keep in mind, this is after i took it off and I admit I didn't know any better and bent it trying to take it off..will fix that and take new pictures.
I am placing the PCM where the stock Fiero ECM was but many can benefit from your useful Post !!!
