The shifter in the Brapwagon is, I'm pretty sure, missing some kind of plastic retainer that fits inside the outer shell and stops it from wobbling around. I think I'm missing that part. I have the outer shell, and it has a cutout down the bottom where a roll pin goes through and fastens onto the inner stalk. On my shifter assembly there's nothing else in there, so the outer shell can move around quite a bit.
Looking at the parts diagrams, I'm thinking I'm missing 1381966 and 1381967 (items #15 and #16 on the below diagram). Can anyone confirm if that's right? Also, can anyone see a reason I can't just make a basic bushing out of delrin and put that in?
