They used a few different Sunroof Motors in the 1989-1997 MN12..
I'll try to break it down for you..
1989-1993 MN12, and the 1993 Lincoln Mark VIII all use the same Sunroof Motor Assembly..
1994-1996 MN12, and the 1994-1996 Lincoln Mark VIII all use the same Sunroof Motor Assembly..
The actual Motor itself is the same between 89-96..The assembly the motor attaches to is what changed throughout the years..
1997 MN12 use a completely different Motor and Assembly..
1991 Ford Thunderbird Sport
