I've swapped in a 1991 5.0 into my 77 and am using the serpentine belt setup that came with it, including the alt. p/s pump and ac compressor. Everything looked OK untill I tried to get a top hose to fit. The 77 hose runs into the belt tensioner and the 91 hose ends up to far past the side of the radiator. Thought someone here might have done the full swap into a Mustang II or something like a 65-68. Didn't really want to go with a flex hose or the cool flex stuff. Already spent time at the parts place looking. Any help would be appreciated.
