After beating National League outfits Torquay United and Altrincham on the way to the last four, Jamie Howell's giant-killers head into the tie at Blundell Park trailing 1-0 from the first leg at Nyewood Lane.
If the Rocks can overcome the National League giants, they'll face either Nantwich Town from the Evo-Stik Northern Premier League or National League FC Halifax Town in Non-League's showpiece final at Wembley on Sunday 22 May.
