I have had issues with those on my '85 Turbo - not the same part but similar and last time I replaced it I went for a OE Mopar unit which has been fine for 15+ years - though I don't drive much - like Carlisle and Moparfest is about it.
The unit listed as replacement on RA for the '74 Cuda was used up to '87 on the GRan Fury / Diplomat / 5th Ave so you might be able to find Mopar one.
I bought a WVE for the Cuda but has not been tested at all yet. If I have issues I will be looking for OEM on that part - thinking maybe I should add it to my swap meet list.

I would also put a gauge in it besides the light.
