WTB 2015 EC300 rear subframe
 

Picked up a used bike, 3 of 4 subframe bolts are sheared and bent. Went through 3 sets of extractors trying to pull one out. Don't want to drill the threads out, anyone in USA have one?

Take to machine shop and have them remove the broken bolts.

I took it to 2 different shops, since the bolts were bent and broke they didn't want to touch it. Hardened steel bent into aluminum and broke off was a lost cause. I drilled them out and put it back together with stainless. At least it'll have some bend before it snaps.
