FR M8509R Aluminum pullys?

I have a new set of M8509R Ford Racing pullys. They don't fit the waterpump on my early 302. I remember seeing them in the Ford Racing catalog a year or so ago and I think they were advertised as "street rod pullys". They are not in the 06 or 07 FRPP catalog. Crank pully is 4 bolt and the waterpump pully has a larger diameter bolt pattern than the bolt pattern on my water pump. They are short 2 groove pullys.
Anyone know what engine/years they fit?
Thanks

Nobody?
I will try calling Ford Racing again, but the last call got no feedback either. The guy I talked with was not familiar with these pullys. They are no longer available, and this must be the reason.....no-one knows what they fit.....

Thanks latamud and D. I have had a heck of a time finding what this thing fits and since it is not sold anymore, no one seems to have any specs. It sure won;t fit an early waterpump. I have a new reverse rotation pump I pulled off the Ford crate 345 HP motor in the Cobra. It seems that maybe the bolt pattern on the fan pully for this pump was larger like Latamud stated. The guy I bought them from on ebay never included the "R" in the number in his add when I bought them, which changes everything. Don'cha just love ebay.....Thanks a lot guys
