Thanks to a mixture of information provided by the Bentley 3 Series Service Manual, generous advice from 3050rpm, and an article written by Karl entitled "BMW E36 Sunroof Repair" found on the bimmerdiy.com website, I've finally managed to align three of the four points of the sunroof with the rest of the roof. There would appear to be some anomaly occurring with the front left corner because it now juts out some.
Most importantly, when reading the Bentley manual you must realize that the language used - "Rear of sunroof should be 2 to 3 mm below surface of roof", really means - "open sunroof slightly from the closed position." I still don't know what is meant by "2 to 3 mm below surface of the roof" because when the roof is opened it's raised above the surface of the roof. Is it not? This minor language error caused confusion from the very start. From there, the interior cloth panel should be easily slid backwards allowing access to the sunroof mechanisms on each side.
The greatest challenge during this endeavor was the small torx screw on the passenger side track. I managed to strip the damn thing from the first turn of the wrench. I will warn anyone attempting this job, it is an awkward angle and requires extreme care! With all the tools and ingenuity I thought I had, I was still unable to remove it. Consequently, I was forced to abort the 'Sunroof Realignment' mission. So, word to the wise, be extremely careful with these torx-20 screws on each side because if you don't, you may end up having to abandon the project just like I did.
