Hi Kay:
I regret I don't have a model for a DC-9, but just for the record (in case anyone else is looking for FliteStar aircraft models and comes across this discussion in the future), Jeppesen maintains a small database of aircraft models at this link:
FliteStar Aircraft Model Exchange.
The models have been created by end users, so, one has to look at them critically and carry out due diligence.
