Claimed COPO

[golfer]

This car has what appears to be a window sticker with the 9561 ordered calling it a "high performance unit". But on the build sheet it has the L 78 engine option listed along the bottom where the options are listed, but it has an MN engine code in the engine code box and COPO tires and wheels were ordered. This is another thing that I can't figure out. Also, the build date of the car was 09D, so its an early car and the engine casting number might be correct - I just don't know and have never heard of a COPO with this engine casting number.
