Looks like 10 splines on the clutch. If you are sure it is 10". 10.5 is more common:

Take the thick rubber spacer off when you check the front shock compressed length. The rear are Gabriel Red Ryders. The number on shock will help me identify them. I can tell you what you need if I know the compressed and extended lengths. I'd crossover to KYB Gas-Adjust.
