Guys, looking at this clutch diagram...does anyone know where #7-8 goes? I'm assuming it is identical part to #6.

I need to order some clutch parts but not sure if I have to get 1, 2 or 3 of these #6-7-8.

They are named in the parts description:
Part #6 = PLATE, CLUTCH DRIVE NO.2
Part #7 = PLATE, CLUTCH DRIVE NO.3
Part #8 = PLATE, CLUTCH DRIVE NO.4

I'm just a bit confused as to why they wouldn't have #7 and #8 inline in the diagram in there correct positioning. Can anyone shed some light on this for me?

I know I could pull my clutch apart to have a look but thought you guys might be able to save me the time.
