I did my front crossover when I replaced the original water pump at 85K miles. The flanged ends were a bit brittle and were starting to deteriorate. I think it was definitely at the very end of its life. I did the rear crossover/heater manifold at 95K miles and it still looked new. I know for sure neither had ever been replaced because I bought it from original owner and friend and know the complete history.
