Driver side mount, inner 6mm. Impossible to see, it was a small victory to even land the allen wrench onto the head blindly. I really shouldve found a chiltons article or something on this job.

After rounding the head, I thought of ways to extract it.. I ended up dremeling a notch at the bottom of the bolt and a square cm of the frame underneath for a screwdriver to fit (lot more frame had to go if I wanted to drill say for a reverse extractor kit). anyway, Yuge failure.

I think I'm done with underneath solutions. Don't really want to drill through the bolt with some fancy bit, the probability of me ruining threads too high.

New course of action: from the top. If I jacked the motor high enough could I fit a ratchet and socket on it? Is hammering a socket over the head in any way possible? and finally the only other idea I have is taking the aluminum arm off, which I am obviously refraining from..last case scenario.(BUT MAY be my last ray of hope::confirm/deny)

need to hear it from the trained veterans
Thanks in advance
