Anyone ever mounted a 3 point shoulder harness seat belt to a roll bar or roll cage? Did you drill through it put a bolt/nut through the hole? Did you weld in a bung? Or maybe you welded on a piece of flat steel and bolted the harness mount on? I have seen all sorts of options, but need to figure out the "best" option. Need to put a shoulder harness in my truck where a roll bar exists. Pics would be great if you have them!
