Well, 2 weeks and a handful of flashes later, I already bricked my PCM in my 96 SS using Jetflash. Followed all precautions, program just crashed.
Anyway, the local U Pull it has a 95 Cadillac Fleetwood and PCM's from there are only 30 bucks. This PCM would work, right?
Furthermore, only other thing i'd really need is a 94/95 knock sensor, correct?

There’s no question whether you can install a 94/95 F-Body LT1 OBD-1 PCM in a 96/97 F-Body LT1 OBD-2. Gets done every day. Works fine, identical harness pinouts, etc.. Yes, minor changes like using the low impedance 93-95 LT1 knock sensor in the 96/97 engine to match the requirements of the 94/95 PCM. The question is whether the B-Body LT1 OBD-1 PCM is an acceptable replacement for the F-Body version.
OBD-1 advantage is elimination of intrusive OBD-2 diagnostics like the after-cat O2 sensors, EVAP vacuum detection, AIR system flow detection, CKP misfire detection (which some might not see as a good thing). Also easier to program with low cost/no cost software, compared to the expensive OBD-2 software.
Unfortunately I don’t know the specific answer regarding the Cadillac PCM, just wanted to put the discussion on track.

Well, turns out, the cadillac PCM works just fine. It was basically just plug and play, and I managed to get a new Knock Sensor on Amazon for only $10.
Tuner Cat was able to repair my OEM PCM for just $25, so I went ahead and sent that in.
Also, picked up an obd2 PCM that was on a Buick Roadmaster, again, was skeptical if it would work, but it does.
The only issue I had was that when I tried to flash the Roadmaster PCM onto my Camaro, it would say that it wasn't for the right vehicle and wouldn't flash. I got around this by simply changing the VIN in the tune, rather than in the PCM, for it to flash properly.
So, if anyone runs into these issues going forward - this is how it works. Also, i'm happy I have 2 extra PCM's laying around incase **** hits the fan again
