2nd Gen Non-Engine/Transmission Seat wont move

[4570]

Was cleaning my truck and moved the electric seat forward . Now it wont move back . I took it all apart down to the little gear boxes that are powerd with one electric motor . One of the gears thats on one of the long screws is split and was jamming it . Any one got an old seat rack they can salavge this gear box and screw assembly out of . Arnie
