1970 steering column question

[JCHansen1]

Hi everyone- quick question, mostly for future reference for me going forward as I'm passing on the car in question- 1970 Z28. Car is currently a 4 speed. I have a question about the steering column- there is an arm coming out of the column just past the firewall in the engine area. Either reverse column lockout for manual car or a column shift car at some point? There is a visible spring about 1" long just past the arm. The parts diagrams I can find for 76-81 columns identify that as an automatic column, and the manual columns have similar arms, but no visible spring just past the arm. Can't seem to find a diagram for 70-76 cars. Anyone know what I'm talking about? Wondering if the car was an auto at some point and swapped. Photo taken from under the car. There is a 3 bolt bracket on the inner driver side subframe rail that is missing too.

That's the correct column...
Here is my brother's 73 Z28 4 spd.

Thanks- nothing looked modified or amiss under the dash, it was only the 76-81 parts diagram that got my curiosity peaked.

Yup, same as my 70 Z project

are you sure it didn't say 70-81?
