Hey Dan,
I went through the same thing,
thread , there's a 9, 10, and 11 inch clutch for these with respective pressure plates. I put the 10 in which has the 6 bolts. I'll check to see what my 9 inch has tonight, but check the bolt pattern diameter, the outer and inner diameters of the clutch mating surface on the flywheel and the clutch to make sure they match. Whoever you buy from should have all these dimensions.
And I'm sure all this info is in some other thread on here somewhere. Try searching for "flywheel" "clutch" and "pressure plate".
Good luck,
Dave
