Shift arm retainer clips

Oh, I agree, I was just being a SA. I have seen nails used on 4-speed shift linkages, though.

On removing the OEM clips, I don't push on the part of the pin that goes through the hole. Instead, I insert a narrow screwdriver behind the largest round part and past the side of the shift lever, then just pry. Comes right off.
hold your finger on that round part as you pry, will save a lot of searching later
