LOL @ YOU!!!

Four points are dangerous... get a five point harness...

 

Well, most people just crazy glue or hot glue (epoxy works the best) the brackets to the frame after cutting their carpet w/ a box cutter but.

If you wanna be smooth and clean, I recomend, sourcing the mount points for your seat and mounting the bracets in those bolts, or go to the back seat in between the upper and lower portion , attach to the frame there if your running a gutted rear interior.

Or get a drill, and tread the holes in your floorpan, run custom bolts? haha
