Hi, hoping someone can help me here. I'm now starting to reassemble my 1972 Raider having cleaned and repainted it. I remember putting the woofruff key for the main drive pulley on the side of the axle/gear box in a safe place where it would not get lost. In fact it was so safe I can't find it now. Can anyone tell me what size the key is? It's an 8 speed gear box. Any help here would be appreciated.
