An 87 model year would be an LTD Crown Victoria, and those has the AOD automatic transmissions. 80 - 86 Ford LTD, 80 - 93 Ford Thunderbird, 80 - 93 Mercury Cougar, 84 - 93 Ford Mustang, 80 - 86 Mercury Marquis, 80 - 87 Lincoln Continental, 80 - 83 Lincoln Mk. VI, 83 - 93 Ford Econoline van, 83 - 92 Mercury Grand Marquis, 82 - 93 Ford Bronco, 81 - 92 Lincoln Town Car, 80 - 87 Lincoln Continental, 84 - 92 Lincoln Mk. VII, 80 - 88 Ford F-Series pickups, 92 Ford Crown Victoria, and, of course the 80 - 87 Ford LTD Crown Victoria all used the same automatic transmission. In the case of the Bronco and F-Series, naturally, the donor transmission would have to come out of a 2WD vehicle, and not a 4WD one.
