i bought a cheap aftermarket set of fronts from rock auto just to use as spares. they were about $150 for both. I wouldn't use them as an actual replacement but figured they'd get me home.
I love these threads. Ultimately I would just pull a second (running) cruiser behind you.
I don't have a second cruiser though so I carry:
90% of the tools I use every day
2 spare fusible links
Spare efi relay.
Spare ignitor
Belts.
Various coolant hoses.
Oem starter rebuild kit
Emergency...
