The 90 only has one O2 sensor so you definitely need it. Sounds like you have a header for the 91 and up. My upstream O2 sensor is on the down pipe, yours I believe is on the header just above the fitting for the down pipe. I will defer to the Renix experts for possible workarounds but you do need it to run properly.
The outlets are different and there are no bungs for O2 or EGR tube.
Have a new downpipe made with an O2 sensor bung welded into ir as close to the header flange as you can. Have them use a shallow bung. You will have plenty of harness to reach the O2 sensor's new location.

Thanks for the info guys. It seems like anytime I buy parts, there is a problem with the year. couldnt wire up the stereo because I was looking at a 90 wiring diagram, but the guy at crutchfield said that the wire colors I was describing were on a 91. I dunno!?

didn't needed a jack or a cheater pipe, all I needed was my 18" breaker bar. Lol

One thing I've learned over the years is that Crutchfield is GREAT for home audio, and for looking up specs on audio equipment that you want.... but that's pretty much where it ends.

Question. On my 01 with np231. Can I just unhook the front Ds at the pinion and hook it up under the jeep. Or does the front yoke of the TC spin in 2HI?

No.
Pundits may suggest that the yoke may spin to what is essentially hydraulic action, since the disengaged sprocket is resting on a moving shaft, but that should be stopped by a good zip ties.

Just take a 5/16" 12-point wrench to it.
Ever see what happens when the front end of a driveshaft drops to ground and encounters a crack in road?

It's only 4 more bolts to remove it completely. Better safe than sorry

NOTE for others who might be contemplating the Rubicon Express 3.5" leaf packs...the indexing pin did not fit in the hole on the spring perch at all. I ended up taking out both index pins and grinding off enough material to fit in the holes.
