Went drag racing last week with my new linelock and digital MSD two step. Didn't work worth a damn. I used the stock micro switch from Hurst to control both at the same time. It was designed to be held with their rubber sleeve to their shifter, not a 69 Camaro horseshoe shifter. I tried small wire ties. The switch button would slide under the ties and not release. Hard to race that way. So I came up with this guy. I bent-up scrap aluminum that I cut off of my new radiator a couple of years ago. The plan was to use this micro switch and double sided sticky tape to hold it to the side of the shifter so my thumb would control it. No reason it wouldn't work and work well. Then I took apart the Hurst switch. Oh well. See the next photo.
