8h 600 Mile Roadtrip - Advice

I'm assuming you have V-groove pulleys.
Throw a pair of extra strength women's panty hose in your trunk too.

Or just buy an extra belt for the trunk, they're cheap. As long as you have a couple wrenches, it's a 5 minute job. But really, a belt inspection before you leave is a no brainer.

My trunk box has points, rotor, distributor cap, etc. I bought a new fuel pump at Carlisle for $10 so that's in there too.

I do wash my windows with women's panties though. I hang a brassiere from the steering column to hold snacks and a jock strap from the parking brake handle to hold nuts.
