Hey, I'm looking at possibly switching to a 67-72 Chevy for my daily driver (currently an '02 extended cab Silverado). The only thing holding me up is the seat belt situation. I've got a wife and two kids still in car seats (the kids, not the wife) and there are only 3 sets of belts in the truck.

Is there any way to safely put another set of belts in there? Do you think the two seats and two adults would even fit? Are the 73-87 benches wider so that they may work?

It's not something I need to do very often, but I'd like to at least have the option. Any suggestions or ideas welcome. Thanks!
