You can get "resistor networks" in dip packages, some come in less than 10 Ohm sizes. You can also get "zero-ohm" jumpers that look like resistors, but are just a body on a solid wire. We used to call them "sanity preservers" when trying to layout single sided PCB's and gave up trying to avoid crossed traces. You could try Dale/Vishay, or any of the larger distributers like Mouser, Digikey, etc, they should have something.
The zero ohm jumpers are good where traces run under them and you don't want to risk a bare wire jumper shorting it or getting a solder bridge. They are also common in surface mount packages.
A final resource would be what are called "dummy parts." These come in all packages and are used for testing PCBs for continuity. Morte likely these are too expensive for your needs though.
