Need some help!!! Will a fj40 with a f2 water pump fit on an f1 (1 Viewer)

[Vinny moccia]

I bought a water pump for my FJ 40 and I was wondering if the water pump from an F2 motor would fit on an F1 and how to tell the difference between them

dont know what an f1 or f2 is i go by year of the truck but if you use the pulleys that go with the pump they fit there are several different offsets i have an early pump on my 2f but used the early pulleys and put a 74 pump on a 64 fj40.i know they work just need the right parts
