I have a older 5 port, I believe that I have been told it is a gen 5 with the black case with a silver head without the fancy design on the top of the head. Where can a guy find a new rod to work with this? I noticed when I pulled it apart that the crank pin and rod have a bit of slop between them, and for the price of the go rods I figured I would just change it. Also what would be the recommended plug to use in it? It's a turbo head, but I think I might be having a problem with the button so if you could reccommend a turbo plug and a standard I would appriciate it. Thanks
