Looking for knock module 16214671

I had my pcm tuned and realized the knock module is missing from the pcm.
Just finished up my Fleetwood and can’t drive it!!! This is nuts!
Of course it’s a 96, so I’m looking at a very narrow list of options.
Can’t afford an LT4 one.... and no one locally has any parts cars. Junkyards around me have ZERO B/d body cars.
I’m exhausting all options. Anybody here have any spare pcm’s
I’d consider buying the whole pcm if the price is right. But honestly all I need is the knock module.
Have paypal, looking for something to ship to 01083 Massachusetts.,
PART NUMBER 16214671

TIA!!! Please help.
