Horsham - if they beat Kingstonian in Tuesday night's second qualifying round replay at the Camping World Community Stadium - will host Eastbourne Borough in the next round.
A clash between Dom Di Paola's Isthmian premier side and Danny Bloor's National League South outfit would be a mouthwatering occsion and create plenty of interest across West and East Sussex.
If it's Isthmian premier Kingstonian that Borough visit, they will meet ex-manager Jamie Howell, who is No2 on the Ks' management team.
The next round is scheduled to be played on the weekend of October 2 and 3.
Hastings will travel to the winners of this week's Poole Town - Chippenham replay - a tough task for Chris Agutter's men, though they are on a great run of wins in league and cup. Poole play at step three - one league above the Us - while Chippenham are at step two.
The other Sussex non-league side still in the cup are Isthmian south east team Whitehawk, who will go to high-flying Southern League premier side Hayes and Yeading - who knocked Bognor out in an earlier round.
Third qualifying round ties have a prize pot of £5,625 for the winners - and £1,875 to the losing side. After that comes one final qualifying round before November's first round proper.
