First take off the rubber cover in the driver's side fender behind the tire, If yours is missing, you'll see a big hole there used to get to your upper A-frame rear bolt. If your Z-bar has all the stock pieces in it, first take off the big nut on the driver's side wheel well, behind the front tire, holding the Z-bar's outside ball mount. You might have to hold the inside with an open end wrench. Unhook the clips holding the clutch and pedal push rods and remove them. If you have a funny looking wire thing around the left end of the Z-bar, leave it on because it will hold your grease seal and plastic bearings in the hole along with the ball. Next, swing the outside of the z-bar with the ball up and out working it towards the big hole, That will unhook the inside of the z-bar and your are going to catch the inside plastic bearings when they fall out. While that is out, now pull that funny clip and inspect the seals and plastic bearings for wear. Whole kits (seals and bearings) are for sale on Ebay if needed. Some also drill a hole and install a grease fitting in the middle of the z-bar and inject it with grease, That's too much grease by the exhaust! I recommend putting some wheel bearing grease on the plastic bearings on the ends and putting a little in the middle. If you have good seals on the end, you shouldn't have to worry about them going dry. I think Chryco has everything else above.
I bought a pivoting transmission jack at Harbor Freight for $35 2 years ago and it really helps pulling and installing that trans.
