Aftermarket knock sensor?

[1owner]

Hi all,
I'm almost ready to start my newly rebuilt motor. Should I replace my knock sensor. It worked just fine [the best that I know], but has been in there a long time and many miles [256,000].
Also if I did replace it, should I go original AC Delco or is an aftermarket one OK?

thanx in advance

I dont think they go bad, but if you want a new one you can get one for a LT1 Corvette.
