Newby here and I really like the 60's series wagons but am a little lost with the model designations. So I know the "FJ" stands for the gas engine as supposed to the "HJ" which is diesel. So North America got the "FJ" models where does the 60, 61 and 62 come in and what is the difference between them? What years were they made?? What size engine is in the FJ's?? Thanks
