Actually Will that part number was a marker light or something from an 87-89 bonneville.
No big deal since it was discontinued anyhow.
I already installed the new spring and tightened it a bit tighter than what it was and tightened the old one too so it opens great now. maybe tomorrow morning I will attempt the STB.
Anyhow back to the "party beverages"
