Can anyone point me in the right direction for what tool I'll need to remove this bottom bracket? 16 irregular internal notches, with 4 being bigger than the others. Internal diameter about 31.5mm. Bike was bought second-hand and I'm planning on adding a BBSH02 motor. I've referred to the Park Tools Bottom Bracket Tool Selection article and been googling for a while now, and haven't found an exact match yet. Am I overlooking something? Any leads?

weighing my options for what to do about the fork on my commuter, a 2016-2018ish Koga Confidence. The rubber gaiter protecting the suspension cracked and water has been getting in, leading to rust and loss of travel. So I pulled the fork off to take it apart and get it cleaned, and planned to patch the gaiter from inside. Unfortunately as I was trying to remove the front fender, I snapped the retaining bolt on the left side. I used penetrating oil, gave it some taps, and used a dremel to cut a notch in the center and quickly stripped the notch out with a flat-head. Then I tried more penetrating oil, a heat gun, a new notch and patiently tapping it out counter-clockwise with a hammer and scribe/awl. Then I made the notch bigger and tried vice-grip pliers and broke the notch off. Now I have a stub. It's too small for any of my reverse-threaded drill bits, and I don't trust my setup at all to safely and accurately drill it out.     The only Koga dealer within 2 hours of me that has an exact match OEM fork for replacement wants 300 CHF ($330 USD) for it. How should I proceed? Should I start hitting up all the metal shops and garages in the city to see if one can extract the bolt for a reasonable price? Should I be looking into 3rd-party rigid forks?

Anyway I gave my stripped bolt another couple of goes, with my dremel, vice pliers, etc but since I don't have a work bench or vice, didn't trust freestyle drilling too much. Found a local metal shop that drilled it out and re-threaded it for
