Davies made a massive 490 appearances for the Welsh side during a 16-year career, but has sadly seen his health deteriorate in recent years.
The 72-year-old has dementia and resides in Bay Tree House care home in Wrexham, while he is also in a wheelchair, complicating his travel to London.
Supporters had quickly picked up on Davies' struggles, starting the campaign, #GetGarethToWembley on social media.
The push to send the former defender to the final against Bromley on May 21 quickly gathered momentum, with Wrexham striker Ollie Palmer working to help, and now he has the might of Hollywood behind him.
"Rob [McElhenney] and I will make sure Gareth makes it to Wembley in comfort," owner Reynolds Tweeted.
"He showed up for @Wrexham_AFC and we'll show up for him. #GarethIsGoingToWembley"
The seemingly successful campaign to get Davies to Wembley was started by Martin Evans, whose wife used to care for former Wales international Davies.
"The amount of love and support this man is receiving from fans young and old is phenomenal," Evans said.
"When my wife gave me this idea I wasn't 100 per cent sure how it would go down.
"I won't stop, I'm determined to do this and the support I've received is fantastic too, from friends and family, to supporters across the world and even number 35 Ollie Palmer himself.
"I heard of how he was and thought it would be a fantastic idea to try and help such a highly respected club legend have a day out to Wembley.
"And a lot of the comments I read on my post were all about how much of a great player he was and a lovely person - my wife agrees that he was one of the nicest people she had ever met."
