Easiest way is to get a remote starter test switch at the parts house (or make one), with alligator clips that hook up to the solenoid on the firewall (or the starter) so that you can send B+ to energize the solenoid and bump the starter. Caution, though, make sure you're in neutral (yeah, I know, obvious, but...).

Another idea you may want to try is to put the car in 4th and roll it forward or backward as needed to bump the motor over. Another way is to get a breakover bar, proper socket and extension, and use the big damper bolt on the nose of the crankshaft to roll it over, usually works pretty well.

Ahhhh! Patrick beat me to it! :-)
