Hi rich. How did you get on with the locker after giving it a good once over. I'm curious if it works with all the grease. You did well to open it up with no issues.musymt have been a good second hand one or lucky. Most of the time the bolts holding them together just snap off. When I've been inside them I've only put a minimal amount of grease back in. I opened up one of the new ones I sell to see what they look like inside and they only have a small amount of grease inside them. I'm sure it will last a good few years now. As for the dog bones. @stan was doing them. Or you can add some weld to the inside edge of them. 3mm I think I've read.
