Water Pump Question ???

I'm not sure how well it will fit the timing cover, but you can try a granada water pump (iron) or a 80's to early 90's crown vic or towncar. The later model non-HO 5.0s are supposed to be standard rotation.
I don't know what timing cover I have on my 302, but the water pump from a 77 granada was the right one. It looked the same as one I saw in the junkyard off a 85 towncar.
