1950 GMC 1.5 Ton Truck with the 248 I-6

Went to go start it and noticed it needed water.... but when filling, water came out of water pump shaft. (New pump, right).

Okay, local NAPA says they can get new pumps for about 120.00 BUT they said that the book only goes back to 1954 for the 248. Now, will the 1954 water pump fit on my 1950????

I want to put a 'new' one one or get one w/out having a core charge (since I'll have the old one rebuilt as a spare).

Thanks for the help. By the way, this GMC is still being used... old farm rig. We don't retire em.... we just use them then rebuild them and use them.....
