Unless the pan is different between the years a coachman and a sportsman are pretty much the same except the sportsman had more options, like the 440, ac, bigger alt, plusher interior etc forgot to include radiator, was already planning to move it from the sportsman to the coachman either way, the coachman is I think, 2 or 3 row and the sportsman is 4 row, not sure if the dimensions are the same, but since the 440 was an option on the coachman it should be a bolt in swap
