hello all, I sold my 91 dually to my father. Still have my 95 that is a work in progress :-laf After pulling his fifth wheel with mine he wants to get a little more power from his now. I am thinking of putting a 16 cm housing on his. I have a 16 cm housing still in the box that was ordered for my 95, will it fit on a 91 non intercooled cummins? Thanks in advance, Dean
