I got my new TFS 1 cam and when I was going to install it I noticed the directions to use the longer pin for 79 and earlier vehicles and the shorter pin for newer. Well guess what? NEither are in there! The place I bouhgt it from said they just ship it how they recieve it and I cant find any place that sells this piece seperately. I'm talking about the pin the goes into the front end of the cam that the cam sprocket slides onto...Any suggestions?
