The fork bolts require a 36mm socket, which Amazon.com was happy to sell me. I took the angle grinder to it to flatten the face since the bolts are pretty shallow. It wasn't perfect, but it got the job done.
Shockingly, I wasn't able to loosen the bolts with my big breaker bar, so I had to put a pipe on the end to get some more leverage. The shovel was used to prevent the fork from turning. It also matches my short shorts.
I only loosened the bolts for now. I will remove the fork as soon as I get the engine out, which will hopefully be this weekend.
