M5 reciprocating assy on E-bay right now. Search under BMW M5 and it should come up. $300 is a great price if the parts are good. The getrag gear box for an M5 was just on there also. Of course, buyer beware. I am seeking a BMW M5/6 engine and manual transmission. I am also going to need the computers and wiring harness. This is for conversion of earlier E12. Has anyone seen one of these in parts yards or online?
