They will take on Fylde at Wembley for a place in the Football League, the Lancashire derby will take place on Saturday May 11.
Manchester United hero Neville has been a big figure in helping Salford secure three promotions in four seasons.
And he recently defended criticism the club has faced for the money that’s been invested into its progression.
“You get a lot of, ‘Can’t wait until you get out of this league — you’re ruining it,’” he said.
“Every time we go away, it feels like there’s a team that is anxious to beat you, a crowd that desperately wants to see us lose. It doesn’t bother me, it can act as an inspiration. But the idea that we’re ruining non-League is just ridiculous.
“Look at Jack Walker and what he did at Blackburn.
“He’s lauded as a great pioneer, someone who loved his local club and invested some of his money in it.
“That’s no different to what we are doing.”
Elsewhere, United’s Champions League hopes faded after they were held in Yorkshire.

Neville had said earlier in the day, that there was nothing he liked about watching Man United play after they continued their torrid run of form.
“This is Huddersfield Town who have struggled all season. You watch them, they haven’t got the quality, but I like watching them a lot more than the ones in the red shirts, to be honest,” he admitted during commentary.
“At least you can identify with them. There’s nothing I like about this United team at all. It’s just awful. Look at them. They’re the most despondent group of people.
“As a manager, you want to like your team. I look at Ole Gunnar Solskjaer, I can’t imagine he’s down there thinking he likes watching this lot – I don’t.”
