93 is still 2nd generation. We have replaced the clutch in our 95 3X. Try to avoid that as it really is not a whole lot of fun.
As far as advice goes, I would stick with Toyota parts. We bought an aftermarket kit and it was junk. They gave us a new and supposedly better kit a year later and we installed it but still not happy. Finally pulled it and put a new Toyota friction disk in with the original pressure plate and it has been fine since.

You will need a tranny jack of some sort as the tranny together with the transfer case is heavy. I used a scissor type and it worked fine. I tried to use a saddle attachment on the floor jack the first time but did not have enough clearance. Had to get a flatter jack.

Get a set of swivel/universal joint sockets as it helps a lot when you are trying to get the bell housing bolts in and out. A bit of a tight fit so the swivel helps. The set I got were 3/8 drive impact sockets.

Make yourself a set of dowel pins. Get some bolts of the right thread and cut the heads off. Screw them in to the bell housing and use them to align the tranny when you put it back in. Cut slots in the end so you can use a screwdriver to remove them. 2 is probably enough.

Have the flywheel ground.

Mark all of the drive shaft parts so you can put them back the way they came out to avoid vibration issues. I used a can of orange spray paint to spray a line on the front and rear drive shafts to make sure they went back the way they came out.

As I said, I did not think it fun by the time I did it the 3rd time in about 3 years but it is basic mechanics. Undo stuff and then put it back together. You need about 3 people to put it back in easily. My son and I were under each side lifting and wiggling the tranny in while my brother in law was under the front with a light looking to see if we were aligned and telling us what way to move it. My brother in law is a mechanic with many years of experience and my son is an apprentice mechanic. They both know their stuff. I am not a pro - just an amateur do it yourself guy. I took the tranny out by myself each time but needed help to get it back in each time. The transfer case makes it unbalanced so it is hard to get it in place without assistance.

Be careful. Use good jackstands on solid concrete etc. Don't get hurt.
