water pump

i checked marine, I dont think.I found old paper work on this car and i think this pump was put on in 1994, it was just a hand written note that listed a bunch of parts put on back then.i am stumped and all local mopar guys are to. i think i am going to put pump on that all my local stores have in stock. just added a holley sniper which has hand held computer so i can keep an eye on engine temp.thanks
