It sounds like you've got a mixmaster rig that's been assembled from a pile of parts. It might be necessary to do a little research on previous owners and see if you can trace things back to whomever did the assembly. When I shipped a military Jeep to California from Okinawa in the mid-1970's, all the paperwork got lost along the way and I had to post a bond with the DMV equal to the appraised value of the vehicle for 3 years before I could get a clear title.
