Correct, the AB 85 only retarded timing by 8 degrees, the AC running unleaded fuel retarded timing by 12 degrees.........personally I would use the AC version......will save your engine........you can tell the difference, AB has a thick seal around the E101, AC is a clean seal.
From doing some research the part# I bought (MD109942) is a primary part number for 86-88, but I also forgot that in the US there were no leaded Cordias so I doubt that any 8 degree boxes were imported here. I'm going to keep digging because there are about8 different part numbers out there for the same box. I'll also check the part number on my box on the car this weekend when I test the spare box.
