The C5 wasn't offered in the '89 Bronco II's. Unless it was swapped in there sometime, it isn't possible.And the TK4/C5 that are the shortest. You don't have a C5 auto in your 89 do you?
The C5 was only offered in '83-'84.
Look at your transmission code on the door sticker. If it is a T, then you have an A4LD.
