Hi Mechainiac, thanks for your note. You are right. I have been aroun on few notes. This site is got so much information that I never finish reading. While awaiting for some help I found a topic on page two. I read a tech note. I will study it tonight. Not having finished the reading seems like it uses part of the current body that holds the drum and the after receives a disk. I do not kno if this disk is from a special kit or comes from stock product. If you know something about it, will be very much appreciated.
