Y-Pipe for 88 Fifth Ave

My tech says he needs a new Y-Pipe for the old lady and gave me Summit part number 40235 as the piece he thought would fit. Summit says it is for a Dakota and was unsure if it would work in the Fifth Ave. Does anyone know if those parts are interchangeable, or what know of any other part numbers that will work, or should I order a universal kit and have a new Y Pipe fabricated?
