Paul, you are correct about the 40000, I had a brain fart!
I also screwed up saying that the pump I asked for fir the R20 engine,
it was a H20 engine.
One thing though, I don't think Nissan built a 4 main 4 cylinder engine.
That should be 5 mains.
Maybe I got lucky with the pump I got from the fork lift shop, but
everything lined up. The only problem I had was that I had to replace
one of the studs that hold the water pump on that was too short to get a
nut onto.
Peace,
Pat
