All right guys...I remember reading some of the postings about the 03-04 Chevy/GMC Ext Cab rear seats not folding down, but nothing mentioned how to get them to fold down and then lock back up again. Did you guys modify those hooks on the back? If the seat is not in the hooks, the seat just wants to flop down. I installed some amps behind the seats, and it kinda sucks that I can't even show them off. Any ideas? Appreciate any info!
