Not without first removing the left & right stainless ‘A Pillar’ trim!… However, there is nothing wrong with using a bead of sealer… just don’t overdue it.
The original purchase order for an ‘81 Avanti would be available from Nostalgic Motors… That document would identify the exact color ( car make & paint code) for your car… plus much other information.
Apparently the AC3311 Studebaker oil filters were painted 3 different colors…..
1) Black
2) Red
3) Red & White
Rumor has it that most Stude Avantis left the factory with the Black version.
