1. Seperated, marked cut line, cut, filed edges, polished with scotch brite wheel the 2 side angles for front seat back. Also seperated and edge prep the lower and top angles.
2. Removed the protective vinyl from the front seat back. Marked straight lines to remove the seat belt tabs. Used a small file to clean the edges up and a small half round file to get the corners. I used some fine emrey paper to final polish the seatbelt hole edges.
