I went through a local salvage yard taking antenna's off of tons of Pontiac's, Buick's, Chevy's ect, and was not able to find a single one with the same threads.
From the same vintage?
At some point in the 90's (?) GM changed the size of the plug on the radio end of the cable. It's possible that the thread size for the antenna changed at some point as well.
I can't swear to it, but I seem to recall the antenna from my '78 Z28 Camaro fit a Fiero.
