After starting my V70 with a screwdriver for 2 months I finally got around to replacing the ignition tumbler. There are lots of good ideas on how to get the sheer bolts out and I am hoping what I came up with helps someone as it was quick and easy. I simply took a Dremel tool with a small cut-off wheel and cut a slot into the top of each sheer bolt so that I could use a flat-head screwdriver. Below is a photo...you'll note that the upper half of the tumbler "frame" was cut a bit too, but that didn't matter as I was replacing that anyways.

I am guessing someone else has thought of this...but I didn't see it posted anywhere.
Thanks and hope this small contribution helps someone!
