This information was taken from the 70-71 dealer parts book.The oil light and the oil pressure gauge take different oil sending units.
With oil pressure gauge on rally dash
part #2495444 up to 3-71 all v/8's
part #3488609 after 3-71 all v/8's
part #3004106 oil pressure light standard dash all except imperial
The different numbers, I would guess, would be just the switch pressure settings are different.
Check with Standard Parts Co they should have what you need

For reference, they're physically different too.

you can test your gauge/wiring by simply grounding the wire that goes to sending unit .....gauge should peg.. Same with fuel & temperature
