It fits in door fine, but the issue is the gear teeth pitch is wrong. The gear will not mesh with the sector.

If I find a motor with gear that fits the 64-66 sector, then becomes very easy. My gut feeling is this black motor will work. THe only concern is if the gear has good bearing below it. If not, will just fail quickly. Note the hole down the gear...I bet the gear needs a shaft with bushing to hold it in place.
