I could use some help

[mike1971c10]

I'm trying to change my son's 69 c20 transmission over from floor shift to column. I looked in the parts book and bought the trans control linkage from a board member. I look at the linkage on my 71 and it's different. Can somebody identify the set up I have the 71. It started life as a BB and 400 trans but now it's 350/350, the bracket on the frame looks original
