Okay, now the instructions. (Note: You don't have to remove the rear of the roof)
Step 1:
Open your roof up about 8-10 inches. This gives you the slack to make the proper adjustments. You do not have to disconnect the roof motor to do any of this.
Step 2:
Remove the rear portion of the California Roof headliner. Rotate the skinny bar that holds it in place to the roof and slide/pry it out. It's in there good, so be prepared to tug slightly. It helped me to pull away the trim ring that surrounds the headliner and roof.
Step 3:
Loosen (don't remove) the 3 nuts that connect the actual roof to the roof frame. They're screwed onto star (inverted torx) bolts. If you're unfortunate like me, you didn't have nuts. Which is why I'm doing this to being with. (Size M5-0.8) 8mm nuts.
Step 4:
Loosen the belts (size T-20 screws). DO NOT allow the belt to completely come off the bracket. Also, you do not have to completely unscrew the bracket, just loosen so the belt moves freely.
Step 5:
Close the roof completely.
Step 6:
Now adjust the front and real seal edges outside to ensure the spacing is equal. You do this by adjusting the 3 nuts on the star screws. You will also need to slightly open and re-close the roof a couple times while adjusting. This allows the roof to reset to your adjustments.
If it's too close to the back seal, use a flat head screwdriver (or similar tool) on the inside of the car (metal roof frame and metal part of the roof) to pry the rear of the roof forward just a nudge. DO NOT use the flathead on the exterior of the roof - you can rip the seal. Once your seal gaps are about the same, leave the roof closed and jump back inside.
**NOTE: There is an actual proper distance for these gaps that you can look up in the California Roof pdf files hosted on this site somewhere. This is the measurement I settled on since I did not have access to the internet while fixing this.
Step 7:
Make sure the 3 nuts are now snug, and that your spacing is still good. If you look at the roof from the outside, you shouldn't have any looseness in the roof along the sides now. If you do, it should be very, very little (barely noticable).
Step 8:
Pull the belts as tight as possible and secure them by tightening the T-20 torx screws.
That's it! Open the roof fully and close it again to test. Once done, replace the headliner and you have a roof that doesn't have gaps.
Yay for accidental education!
