Thanks Jake, but I'll buy new ones. This journey has not been a budget problem, it's mostly driven by the time I have and people I don't know yet because I'm new to the area. Everyone's been real helpful and that's cool. These 12a parts are like diamonds or something. I don't really want to be out scouring Craigslist all the time trying to find parts and storing them just in case.
Not that I have a dog in this fight, but it makes me wonder as a small and regional class why IT7 doesn't evolve to Webers and 13b with a weight penalty to provide some room for growth. Hell, IT even allows for Webers but not on rotaries (although not the 48 IDA that EP uses).
