Lowestoft Town went through to the FA Vase final 4-3 on aggregate despite the shock of losing 3-0 in their semi-final second leg at Whitley Bay.
The Trawlerboys got off to a nightmare start, as the North East side scored three times in the first 19 minutes.
But their four-goal first-leg advantage proved enough to take them to Wembley.
Joint manager Micky Chapman said: "The boys dug in. They were awesome in the second half. We said 'you've got to be united' and they've proved we are."
Lowestoft will now play Kirkham & Wesham at Wembley on Sunday 11 May.
The Lancashire side ruined the chance of an all-Suffolk final by completing a 4-2 aggregate win over Needham Market.
