Having a few problems if anyone had these? So once its all in the housing and the circlip is in, which at first using the small o ring was too tight and the gearstick couldnt move without alot of force. Ive taken the o ring out and lightly sanded the plastic ball, as on side to side movement specifically was notchy and again required force to move. Sanding kinda helped but the notchiness is still there so would need lots more. Ive put it back together and tightend the 4 bolts fully then slackened them off, now the stick is extremely stiff. So is it just the case to keep sanding the ball until it works? Huge amount of effort already, I might just stuff some electrical tape in the original housing to take away the play.
