Sorry, but allthough the subject is the same, the content is not exactly the same in the two massages. In the previous massage (in the Technical section) I asked about the the central link purpose, and I got some answers, In the last massage (in the Lifting machines section) I quote the previous massage and added a new question about metric forks. I thought that the suitable arena to ask these questions is in the Lifting machines section because and according to the detailed title of Lifting machines section which includes attachments, parts,and components disscussions...
But, really this is not the importatnt thing to argue about, maybe you are right and maybe you are wrong, lets be practical and try to get answers to the questions (olds and/or news).
Thank you
