I have a customer with an old 3035 with an srdf-2 on top. The back part of the top left cover broke and I found a part manual and ordered it. Part number 3AL04120. The new lid came in and it wasn't til I tried putting it on the machine that I saw it was different. It is almost the same but the edge on top is much thinner than the one that came off. We went to a company that sells KM parts. They have researched and double checked and can find no revised part number or change. Is this something anyone has seen? The SRDF-2 is dated 2006, if that matters.
