I have a '69 with a 351w automatic on the column. The linkage arm popped off of the arm on the transmission. No big deal to fix as it looks like it is just attached with a pinch ring. The shifter on the column does not seem to want to move any further than N though. I have never had any problems with it prior to the linkage arm coming undone. No issues with the arm on the transmission either. It seems like it is all in the column. Anyone have any thoughts?
