Me and my buddy replaced a water pump on his 1985 custom deluxe 4 x 4 chevy truck..you took everything apart in record time and after installing the new pump and putting everything back together we have this one clip we have no idea where it goes we think it goes some where on the adjustment bracket for the altenator if anybody has a reference guide or a picture facing the water pump with the fan blades and housing off so you can see the pump , altenator and everything surrounding if would be helpfull THANKS
