If you import the 183 observations from MPC into Exorb (http://chemistry.unina.it/~alvitagl/solex/) and then load that into Solex and run a close encounters scan, you will end up with almost exactly the same result as is displayed on the jpl site. i.e. 0.0007 au.
You can also use Exorb to generate a large number of Monty Carlo data fits and then run them all though Solex to generate a histogram of close approaches.
Do you need the full version of SOLEX or will the Lite version work?

There are now 213 observations in MPEC, and after find_orb discarded 4 outliers, SNP now predicts 64822Km at altitude 65° from a Abalos Undae, Mars (81N, 83W) at 18:37 UTC on 2014-10-19. With a bit of hunting I might find where it will be nearer to the zenith at closest approach.
