Not an expert but here's what i did (or what I remember at least)...
1. Headliner needs to be installed (if you removed it).
2. I riveted in the lower rear window finisher.
3. I riveted in the b-pillar finisher.
4. I put some silicon sealer on the rivet heads.
5. I installed the horseshoe shaped window seal which goes around the top, back and bottom of the window (I had to trim my OEM seal a little).
- I started at the bottom corner right where the seal changes shape... and worked away from there.
6. Install the window on the (black) window bracket, with the seal and cotter pin.
- Test fit the window in place (it's good to have a helper for this, maybe put 1 screw in (I believe there are 4), they screw in to the b-pillar.
- The reason for the test fit, is because I needed to trim the bracket window seal as well. Do a little at a time and retest fit (I trimmed my passenger side a lil too much )
- I also had to make some additional cuts in the horseshoe shaped seal so the seals would fit nicely.
7. Before installing it, put some dabs of silicone (I had a black automotive silicone (whatever that means)), in each corner,
- Screw in 4 (possibly only 3) screws in to b-pillar.
- Re-installed window latch.
8. Celebrate.
