I recently called my local ford dealer and the parts guy said E3uc3de73ca is no longer available from ford and no other dealers had it in stock. He did not mention any other numbers that it may have been superseeded nor could he confirm that it is a double pulley. He was kind of enough to tell me due to further research showed that it was belonged on a 83 ford E-250 van with the 7.5 l motor (460). hope this helps.

If you want the ford double pulley, go to the junk yards of America because ford no longer stocks, makes, or has them available. Period. I tried all numbers listed in this forum.
