as I was working on my engine swap, I pulled my MP166K lockup torque converter out of my A500 to replace the pump seal, and noticed a nice size crack in the hub. since I'm on a deadline, I just tossed my stock stall converter back in. my question is, can the hub be replaced/repaired, or is the converter scrap? I presume at the very least the converter would have to be fully rebuilt/taken apart? any places people recommend to rebuild it, and approximate cost?
