i know everyone says that you cant use them for a 5.0, but has anyone actually had the 2 side by side to compare? aside from the bell housings, whats different? this guy at a mustang wrecking yard is telling me the only difference in the input shaft is that the foxbody shaft is 1/4" shorter. is that correct? if so, it sounds like all i would have to do is swap out teh bell and im good, right???
