Jason, what are you going to do with the old pieces? I'd reuse the scat tubing inlets off the front to make a new set of baffles, if you don't want them.
First time I made a set of baffles, it was $700 to just go buy a new set. By the time I was done making mine I well understood the cost, since I had way too many man hours involved on top of the tools required. Now, they're double that price. Might still be worth it.
