I am looking at several AOD's from 1989-1990 and all of them are Ford Crown Victoria or Grand Marquis....I know this has been beat to death, but I'm not finding anything conclusive in my searches online. So I looked up in AllData the tailshafts available for Ford/Linc/Merc AOD's in 1989, they are
15" long 7 tooth speedo gear - E8AZ7060B
16" long 7 tooth speedo gear - E8TZ7060B
and
15" long 8 tooth speedo gear - E8AZ7060A
16" long 8 tooth speedo gear - E8LY7060A
So I assume that the Ford/Merc have a 15" tailshaft and the Town Cars got the 16"...can anyone confirm this? If there is only one inch difference my same driveshaft should fit because it just slips over the tailshaft and has some extra space to play with. Also swapping tailshaft housings is no big deal. 10" for the Fords and 11" for the Towncar (I measured mine)
If all this is correct a Ford Crown vic should fit right into a lincoln town car.
