The fiero store are out of stock of the holley scoop until november. I got one a while back but i cant get it fixed properly. I had one before on a 87 4 cylinder model and it fixed ok. I have an 86se v6 and for some reason the 2 screws in the top wont fix tight enough to hold it in place. The stock trim item stays in place even without the screws. The only difference i can see in fitment between the stock part and the holley is that the stock part has two flanges that hold the bottom in place but the holley does not. Going to try it on someones elses fiero next week to see why it does not fix properly. It should just be a case of screwing it in place.
The "Holley" one also has two tabs on the bottom that hold it in position, if you dont have these you have a broken scoop.
If the screws are falling out its likely that the two plastic grommets in your 1/4 panel that they screw into are stripped. Those can be pinched from the back side, removed, and replaced with others.
The fiero store scoop is not a holley item (nor do they claim it is) It says "Fiero" on it and is a replica of the Holley scoop. (I've had both)
That being said I have one more genuine Holley scoop left, I just sold one locally and could be conviced to let this one go for the right offer. The offer would have to be more than the replica scoop from the fiero store for me to consider it though.
Hey adrian, your fiero scoop should still have those two tabs that you can see in the picture on the holley one. If it doesn't then its likely that both were broken off and you are out of luck on using in without fabricating new tabs for it. (which shouldn't be hard)
