Charley, your old 69 L-78 ragtop Camaro that now sits in my garage
has both XT and IF wheels. The buildsheet code for the wheels says "XT". A Pontiac enthusisast once told me the "IF" wheels were from Firebirds, but they sure seem identical. Perhaps both types were used on Chevrolet as well? Not sure why they would have a different code.
