The original PP and clutch were 9 inch. Not that that makes a difference. The PP should have the fly weights on the three arms. The weights create extra force against the clutch as engine RPM increases. The weights usually do not interfere with the bell housing casting for a 10" clutch but it is worth checking out. Is there anything under the fly wheel bolts that would make them extra tall? Like lock washers or a thick plate that retains the crank shaft dowel? What you have pictured above looks good to my eyes, the clutch plate springs are necessary. The clutch will typically wear down to the rivets. If you measure that depth and add it to the head of the bolts with a glue you can find out if the spring will touch the bolt head as the clutch wears.
