Thanks for the info. Is this the blade you are talking about? As far as getting in there with a dremel and starting a notch. I don't think it's going to happen due to being such a restricted space.I've had good luck with the Lenox "Metal Lazer" blades. If you have room to make a tiny starting groove with a dremel, it helps the blade stay put because the teeth are small like a hacksaw. Haven't chopped any shocks off a 200, so i can't help with the other question.
