Hi, I have a 13BT engine which needs a rebuild as one of the piston chipped on the edge. I has the gearbox with transfer case and also has the PTO attached. The gearbox is still in good condition. Comes out of 1988 Toyota BJ74. Done 250.000km. power steering and alternator rebuild by previous owner. Air conditioner unit needs new bearings. Am presently dismantling together. best keepas one whole package as hard to get parts for these now. I am going to install 2014 1KD engine.
