Thanks to Kev Moose I got what I was looking for in my last post. What I require now are.... Horizontal rocker cover and belt cover. The Oil cooler is held on the front cylinder by two lugs which are in turn part of two auxiliary covers on the head. The rhs cover doubles as the belt tensioner/bearing carrier. The lhs cover blanks an oil way and a coolant port. I have them located in Germany on eBay,but I'll try here first. Thanks in advance.
