i had to hack saw off a non-drive side crank. I think I somehow buggard things up with the proper crank removal tool - or more likely I had the wrong head size on the crank removal tool.

I think I might have tried one of these: https://www.autozone.com/loan-a-tool...80720135940:s#
But I don't see in the picture what goes on the "back side" of the crank. I will check when I get home if I don't see a post saying you have resolved your issue.
