Checking my records, I did replace the timing cover (the original failed) and I cannot remember if there were two versions. I think there is just one for both pumps.
I did manage to find the pump box but it is a little worse for wear. Details below. Hopefully there is enough there to at least point you in the right direction.
Just checked the Ford Performance parts catalog and I reckon the pump I have is M-8501-F351 and the timing cover M-6059-D351
