It's not necessary to drill the hole all the way through the saddle when using the headless bolts. It helps to have a drill press.
I don't have a drill press and was just planning on drilling through the saddle (I am just a weekend warrior doing a few track days a year, the jacks will not get heavy use); I got the headless bolts for ease of removal in case I needed the jacks for my wife's SUV. Will this be ok?
