was told it was a chrysler.It looks like a 904 but casting # does not match. tail shaft has ps448d-1 stamped on it it also has 036-8 in large cast on both sides of bell housing. was delivered with a360 motor date code of 1979 if that is any help.all the # are pretty clear except for the 0 in between the 2s I am guessing it is a 0.
