Sorry, when I didn't see you reply, I assumed that you had figured them out. I'll get out in the garage tonight or tomorrow morning to have a look at mine.
Dont know about Ed's, mine are from a 93 SC Im assuming the first part is the year and some sort of Julian date. The tensioner is the same. But if its any help. Mine are all.....E9SE-6B 209-JA.
( Let me know if you need one. I will send it free plus postage and its got a steel pulley)
