I have a abu garcia 7500c3 I picked up that is having some issues. I think I figured out what the problem is. When you remove the reel assembly on the top of the part that you screw the actual reel on to there is a small C clip that clips on at the very top. This seems to stop your reel from pulling out. Someone apparently took this apart and removed that piece and never replaced it. What is that part called and where could I get one? Are these the same size on a 6500 and 7500? Thanks!
