I drilled and tapped a 1/4x20 hole andplaced a bolt. Workin so far. Broke a couple bits and 1 tap. Oh well. Thanks for input!!Just bear in mind it's not going to be as strong as the original and if I'm correct the spring wrapped around a round "knob". Sticking the end of the spring into a hole it will rub on a rough narrow edge and will prolly snap soon.
