Hi Ivan,
I installed a Beta 60 in our W42. The install went pretty well. We had the engine mounts on the front of the engine ( bow end ) slightly changed and re welded. Used the original transmission. The only issue though was that the forward / neutral / reverse was backwards. I made a plate with a system to correct that. I will add some photos of the mock up of the forward / reverse system. Engine and mock up of new fuel management system.
I may have to send separate reply in order to send additional photos.
Best,
George
