Well . . ..
To start with, turn the engine to top dead center (always do this to pull the distributor). You do that by making sure the "0" timing mark on the pulley lines up with the marker pin. Then look down in the oil filler hole. You should see a dimple in the intake cam. The dimple should be split by the "straight edge" of the oil filler.
Remove the distributor cap. Then undo the two 12mm bolts that hold the distributor in. Then you unplug the electrical connections and remove the distributor. (It may take a bit of a tug to get it started on the way out.)
You will see the external O-ring on the base of the shaft. It is fairly obvious how to replace it. Just roll it off - then lightly lubricate the new one and roll it back on.
(Note: If you don't lubricate the O-rings, you will have wasted your time, because they will not only be hard to reinsert, but you will damage them, and the new ones will leak as badly as the old ones and then you'll be pissed at Jody for selling a defective product when in fact it was your own damn fault!)
Now - look inside the distributor where the electrical parts and rotor are. Is it oily, or is it nice and clean. If it's nice and clean - skip to the reinstall phase.
.................................
If it is not clean - icky with dirty oil and such - the inner O-ring needs to be replaced. You will need to drill, and then drive out the pin that locates the gear on the shaft. I recommend mounting the distributor in a vise and using a drill bit that is about 1.5 mm smaller in diameter than the pin. Mark the position of the gear on the shaft with a sharpie or a scratch awl. When you have a hole through the center of the pin, or at least about half way through, you can use a drift the size of the pin to drive it out.
Once you get the pin out remove the gear (you marked it, didn't you.) then you are set to pull out the shaft. Hold the diostributor with the cap end facing up (so you pull "up" on the shaft).
Make sure when you pull the shaft out that NOTHING gets disturbed on the top end - those little field pickups are VERY picky about where they are.
Once the shaft is out, you can roll the inner O-ring off, and then lubricate and roll the new one back on. Then CAREFULLY reinsert the shaft into the housing. Once the shaft seats, you can replace the gear (align the marks) and drive the roll pin (provided in the kit) in to hold it in place. You are ready to reinstall it.
.......................................
Make sure the distributor shaft turns freely, and has no excessive free-play. There is a dimple in the distributor shaft (near the pin) and one on the housing. Line those marks up. Holding the rotor stationary (very important), turn the distributor to where the rotor is pointing at the ground. Insert the distributor - and still holding the rotor stationary with respect to the housing slide it in. As you do, it will rotate about 60* clockwise. Again, make sure the rotor doesn't turn with respect to the housing (it will turn with respect to the motor). Once it is in, check to see if the bolt holes line up. If they do, you're almost done. If they don't note how much they are off and pull it out and try agian, adjusting for the amount of error. (Note: If you do this part right, you should have no problem starting the engine and re-timing it. In fact, if you mark base with respect to one of the bolts before you loosen it, and line everything back up right, you shouldn't even have to set the timing.)
When you've done this insert the bolts and tighten them just past finger tight. Reconnect the electrical plugs. Look at the bottom of the distributor cap, there should be another large O-ring around the base - where it sits on the distributor. If there is, replace it - if there isn't put the new one from the kit in there. Then reinstall the distributor cap (or - it might be a good time to think about replacing it).
Start the car. Time it. Torque the distributor hold-down bolts. Clean up the area and close the engine cover. Have a beer.

[b]We are changing the solid pin to a spring tension pin to ease the install procedure for customers.
I have the pins in stock, and David (Two's R Us) will have his next week.
