[HI Cobra]

I have a leather boot that I sewed so I know that isn't the problem. I pulled
it and checked that the shifter was tight (it was) because it came loose a while back and gave me a scare but once I put one bolt back in, added lock wshers and tightened them both up no more problems there. It almost feels like it isn't quite going all the way in, so I have to hold it there to back up or it just pops out - no grinds. Everything else feels fine so I was wondering if
any one else had a similiar problem.
