Have a 2004 Z71 Suburban...90K miles on it. We are expecting baby #6 in August. Need to convert my 7 passenger to an 8 passenger. Is it possible to switch out buckets for a bench? If so, willing to trade my leather buckets for a leather 40/60 split. Can this be done? If so, would safety of seat belts be compromised? No one at Chevy has been a help with answering questions. Their solution is to buy new...which we don't want to do. We live in Connecticut...thank you in advance.
