Crankshaft Pulley part#?

[Bugsb70]

I need some help with part numbers, I need to replace the crankshaft pulley on my 1970 F-100. The engine is a 302, two belt pulley with a four bolt pattern. I have looked for the part number on the face of the pulley, but it is not there. I have looked online for listings with part numbers and could not find any going back to 1970. Anybody want to suggest where I can find online listings or where to find the part # on the pulley I have?

the 70 with the four bolt pattern is the new design. the old design was a three bolt. it fits 69 and older. if you need a different one try the parts wanted section.
