Gary,
I just happen to have my
oil pan off so I could drill and weld in an
oil temp plug but I ran into
antifreeze (not good) so the pan is still off.
Anyway I have a stock Ford
oil pan and Ford windage tray. The back is 1 1/2 high and the front before the oil pick-up is 1 3/4 (1 11/16 to be exact).
I hope this helps.
