This is a what we believe to be the correct production 1969 BOSS 302 pulley for the C6AF-10300-A die stamped 42 amp alternator. It's the largest pulley Ford produced from 1965 till 1970 except for the Hipo pulley that was used for other applications.
The reproduction 2.62" single sheave pulley made today to replace this pulley is a smaller diameter, not die stamped and it doesn't look exactly like the originals but its the best pulley available.
1969 BOSS 302 owners commonly believe that their car came from the factory with the 55 Amp C9ZF-10300-E die stamped alternator and the large 3.87" C5AF-10A352-H pulley. Bob Perkins, Ed Meyer and our research indicate that all 1969 BOSS 302's came from the factory with the 42 Amp C6AF-10300-A Autolite alternator and the 2.88" C5AF-10A352-L pulley. Bob did leave the possibility that only really late production 1969 BOSS 302's had the 55 Amp C9ZF-10300-E with the large 3.87" C5AF-10A352-H pulley. Heavy Duty Battery option still gets the 42 Amp alternator.
