I saw the new conversion kit for the CRT .5 on Ebay tonight. It includes the same parts tree shown in the second post, but the motor mount is different. It is a 3-piece mount that attaches the motor to a rotating cam and uses that to adjust gear mesh. The listing said it was Ofna part number 40990, but when I searched online nothing came up.
