Pistol Grip Shift Lever w/ Push in Shifter?

Well on mine I have the slip in type pistol grip on my Duster. And it slid right in. There are these spacers on each side inside the shifter that locks it in. I've seen people drill thru and put bolts across the shifter, spacers. Two holes upper and lower to hold the handle in place. Either way it won't come out. Ed
