When I got my 300E the seller had let the shift bushings go for way too long...as in, the bushings were completely gone and the shift rod had been rattling around for so long in the eyelets that they were enlarged. Consequently the replacement bushings don't fit as tightly as they should and there's still a little bit of play in the lever. It's tolerable but I want better than that. I'm thinking of trying to dab some JB Weld on the bushings to take up the slack. Is there anything else I can do?
