what to do for radiator hose

When I swapped out for an aftermarket radiator I was able to get the correct upper & lower hoses by the application ('72 Duster w/318). Since some of the later A bodies came with a 26" radiator you ought to be able to find a correct hose. Unless the radiator has some different size outlet...
IIRC, I had to trim the lower, but not the top hose.
