Shift Linkage

Restoring a 1970 Impala 2dr. 350 w/3 spd column shift. I've got a box full of shift linkages collected over the years mixed in with the OEM linkage. The 3 spd was removed in favor of a 4 spd years ago. Now I have no idea what fits. Can anyone provide a photo or scan of an assembly manual showing these parts so I can try and match up the right linkage.
Thanks
