Default Crank pulley size

Offhand, does anybody know the diameter of the 69+ crank pulley? I need a new one and was planning on ordering one or seeing if I could find a good used one.

Do you have AC or not, as I believe they are different?

Either 8" or 6". Performance activities prefer 6"

AC pulley is a Crank disk; all same for all PMD V8s 67-72

No ac and i ordered a 6 inch from cvf racing. They had a lightly scratched pulley discounted so I opted for that.
