by Sam from Monticello, Iowa on May 10, 2014
Decent product, more restrictive than older design, less prone to breaking though. Note especially for the older casting y pipes, my new shutters did not just fit right in. My castings were not the same size as plastic ring and the plastic will break easily if forced. I had to hand file the y pipes to fit these replacement water shutters. But mine is a 88. Little hand tuning and mine fit fine, work very well. Might just be mine, but I thought I would throw it out there if I'm not alone with imperfect cast aluminum 4" oval y pipe.
