oilburner Posted October 6, 2012 Share Posted October 6, 2012 (edited) I thank they will interchange, I know a guy that has one of each, complete engine and transmission, he wants 1500 a piece for them, one is a 237 with a 6 speed and the other is a 250 with a 5 and a 4, the both came out of dm 800 coal trucks the 250 is a 72 model and the 237 is a 75, but that would be a long ways for you to come get them. And they both have jacobson jake breaks on them.
