Mar92Yota4x4

So im really looking for help here ...i have a 92 4runner 4x4 automatic ...i saw an awesome post from mopar_runner on how to take it all apart ..the only thing i couldnt see from the post is my problem...i shifted from reverse to drive and heard some plastic break and a approx 4in spring hit the floor..now my shifter is really loose..it still engages in all gears but is loose ...I took it apart and retrieve the spring but have no idea what it was attached to… Please help
