I looked where my engine serial number was suppose to be and there's nothing there and there's a 70 where the Production code is. Is there somewhere else I could find the engine code or serial number on another part of the engine other than on the left side between the spark plugs? I also could'nt find any #'s stamped into my rear end and I need to know which one it is so I can replace the wheel bearings. Can someone help me? My e-mail is jefferyp1@cox.net
