Its very easy to build one using a DM800 and an R model cab, and this is what I have done. Thanks Ben, I appreciate it. As far as ebay, Ive been digging for awhile and havent found much. Ive heard about an Australian Mack book, 50 years of Aussie Bulldogs, that is currently being sold at Australian Mack dealerships but I dont know how to get one.
