Can you figure out correct gearing by comparing FDR and rollout on another car that is geared correctly even when the motors being used are different? Is there a rule of thumb?

Not really, because the motors are different. You can use somebody elses gearing as a starting point, go down a couple of teeth to be safe.

Like the post says here above, you can use somebody's FDR as an indication to start with...
