Somewhere in all this please tell me you put in an actual oil
pressure gauge, either for test or permanently?  You can go around
the barn forever replacing parts (in electronics we called that
"shotgunning") but if the oil pressure is in fact below the standard
then you're never going to fix the alarm because it's already working.

Ok, I know you didn't, but please do.  As long as I've been around
here people have been resistant to actually testing oil pressure when
troubleshooting an alarm situation, but the whole point of the alarm
is to tell you to test the oil pressure!

It's at least as likely that the oil pressure is actually low as that
the alarm has failed, particularly if it's going off at exactly the
time you'd most expect a marginal oil pressure problem to show its
nasty head -- coming off a high-speed run in hot weather.
