hows it going guys, again im looking to fix yet another problem with my z. so the tensionor broke and so "caused" the camshaft sprocket to begin to fail. it clicks a bit with you pull it, and the other one does not. so Does anyone here know where i can purchase a 1990 camshaft sprocket for my z? no local store has them in my area and ebay doesnt either. is it possible that i could use a camshaft sprocket off another nissan? if so, which one? PLEAAAAAAAAAAAAAAAAAAAAAAAASE help! thanks guys.
