Lonnie had requested for a picture of my tach bracket. It was designed to keep from drilling holes in the top of the dash. The plate is just .125" aluminum bent in the vice. The round mount was made from 2 pieces. The top is .500" aluminum drilled and tapped at each end 5/16. the bottom was another piec of aluminum tapped 3/8. The two round pieces are welded together. when its all bolted up you can pivot the tack anywhere you want.
