So I did it. I just drilled 2 7/16" holes inbetween and inline with the other seatbelt holes. Used the included hardware from the belt that I bought at shucks. I'll be replacing the modern buckle with one being sent to me from another member here to match mine. The color of the strap is just right - It just looks new. The job was easier than I thought it would be, which is opposite of the way it usually is when I tackle a project! But no fat guys(or gals) allowed. This is for my son's booster seat.
