There is a gentleman in SoCal that just did the swap the other way and will have most of the parts you need.

You will need the following

Transmission
Flywheel with bolts
Clutch
Clutch cover or pressure plate with bolts to attach to flywheel
Manual specific PCM for a 97
Clutch pedal assembly with clutch safety switch
Clutch master and slave
Manual trans CPS
Shifter floor plate
Shifter boot under console on the floor plate
Shifter boot on shifter for the console.
Transmission specific mounting bolts and clutch inspection plate and mounting bolts.
Motor plate between transmission bell housing and back of engine block
Drive shafts for manual, front will have to be longer and larger in diameter typically, rear will be shorter.
Make sure the trans has the reverse light harness on it. It will plug into the harness that the auto adapter harness unplugs from.
You may have to find a way to defeat the NSS circuit to activate the clutch safety switch. They vary from rig to rig as to how they will need to be made to work.
The auto shifter bezel has a light. Just remove the bulb and tuck the harness and socket back up under the front of the console. That how it comes for the manuals.

Other than that, it is a basic swap. You will need to un-bolt and remove the auto trans mount adapter from the transmission mount and belly skid and then the trans mount will bolt up directly to the belly skid.

If you do the swap and need some of the parts, I may have them at a stellar price likely not exceeding the cost of shipping. I've done several of the manual to auto swaps and always have a few parts left over. I know for sure I have the pedal assembly, clutch master and slave, clutch safety switch, CPS, flywheel, clutch cover, clutch disc, floor plate, lower shifter boot, and maybe the reverse light harness all of which you are welcome to for the price of shipping.

I will however, not do a quote. I will ship it the best way possible and pack it as well as I possibly can and then tell you how much it is, so you either want it and it's worth the freight bill or it's not.

I'm not going to do any kind of transmissions swaps, but if I had known more about offroading when I bought my Jeep, I probably would have tried to find an automatic.

Automatics have a few benefits over manuals.

Autos have different gearing which gives them an advantage
Autos shift more smoothly than a manual which puts less strain on the drivetrain
Autos keep you from having to worry so much about what gear you're in while traversing treacherous terrain.

X2 to all that. Plus a biggie, the torque converter in front of an automatic transmission provides 2-3x low end torque multiplication. True. Most hard core competition level off roaders converted to automatics years ago for those reasons. The crew who has won the EMC class at King of the Hammers the last four years in a row ran automatics.
