Is it possible? I cant find any Chevy Service/Parts/Accessories guys at any dealership that can confirm yay or nay. One guy suggested comparing the build sheets of a HC to and LS (or any other model with bench) to see if the bolt patterns are the same, but that has Google stumped, too. Anyone know if the frame bolt patterns are the same under the carpet, and (even more complicated) would there be center seatbelt attachements as well? Thanks all!
