Yeah, your year probably had a metal ball on the end of the adjuster that bears in the clutch fork pocket but the parts in your illistration will work also. There is nothing holding the ball on the shaft....an none needed if the adjuster stays tight against the fork but yours just fell off when the spring broke. You can make one out of a lug nut or buy a new one (you'll probably have to get a whole kit) on e-bay or through the typical resto sources. The return spring is nothing special but needs to be reasonably close in length. The strength of the spring is similar to the one attached to the E-brake ratchet. You should be able to find a universal replacement and modify the length.
