Hey Paul, just looked at my Brownells catalogue again..........Pacmayr triple magnum on page 442 is 1.5" thick and there are a bunch of different spacers on page 440........but it sounds like you got it under control. The only thing I don't like about belting and some truck liners is they have threads in them which show when you grind them. I have seen other bed liners that don't though...........
