i know it's pathetic to restore a 94, but it's a great truck. i'm stripping it down to repaint, but i want to upgrade the interior. My question is... will interior door panels off of newer trucks fit? Passenger side door needs replaced and i need to know which years can interchange... and last but not least... my stereo system needs at least 1 extra battery, are there batteries that can be installed inside? any help would be highly appreciated. thanks...
