65 Chevy c10 Chatter in steering column

[mrdave03]

Steering column chatter three on the tree shifter?
I have a 65 Chevy c10 with three on the tree and when I drive uphill or even on flat ground accelerating slow the column chatters quite a bit. If I pull the shift lever towards me it shuts up. I pulled the wheel and covers and I see no way of tightening anything. Anyone have any ideas? I also checked the upper column bearing it seems ok. It feels as if it is in the upper part of the steering column around the shift lever but am not sure.
