The Crusaders were forced to promote back-up hooker Ti'i Paulo after Corey Flynn broke his arm in last week's semifinal defeat of the Hurricanes.
However, the Waratahs are in the happier position of being able to reinstate their first choice rake Tatafu Polota-Nau, who missed New South Wales' progression to the final at the Sharks expense with a hand injury.
Apart from relegating Wallabies hooker Adam Freier to the bench, coach Ewen McKenzie has stuck with the starting line-up that impressively dispatched the Sharks 28-13 in Sydney.
Europe-bound former Wallabies No.8 David Lyons has been denied a farewell appearance at AMI Stadium after his hamstring failed a fitness test. His place on the bench has been taken by Beau Robinson.
The inclusion of hooker Paulo is the only change to the starting 15 that comfortably secured the Crusaders' ninth appearance in the tournament finale by defeating the Hurricanes 33-22 last weekend.
Flynn lasted 12 minutes before breaking an arm, robbing the Crusaders of a wealth of experience.
While the injury is bad luck for the experienced hooker, it has presented another opportunity for his regular understudy, the 25-year-old Paulo, who has already experienced the busiest season yet in his representative career.
A Crusader since 2005, the former national age-grade captain had appeared for the side on just six occasions prior to featuring in 13 of the 14 matches played this season.
"It's obviously bad luck for Corey, but we have every confidence in Ti'i," said Deans, who heads across the Tasman to coach the Wallabies on Monday.
"He's played very well for us when given the opportunity, and I'm sure he will do so again."
The injury has also allowed a promotion for Crusaders wider training group member Steve Fualau, who comes onto the bench as the only personnel change from last week's match-day squad.
The front row aside, the Crusaders will otherwise field a settled combination.
"We've come through the semifinal well to give ourselves the opportunity," Deans said.
The two teams previously squared off in the 2005 decider when the Crusaders prevailed 35-25 to annex the last Super 12 title.
Fullback Leon MacDonald, centre Casey Laulala, first-five-eighths Daniel Carter, No.8 Mose Tuiali'i, flankers Richie McCaw and Reuben Thorne and prop Greg Somerville remain from that playing roster, among the side that has been named today.
The final also represents the end of Reuben Thorne's first class career in New Zealand with the former All Blacks captain heading to play in Japan.
Caleb Ralph is also bound for Japan and is unfortunate to have a muted farewell given he could not force rookie wing Sean Maitland from the bench. Ralph ends his 135-game Super rugby career on 58 tries, one short of competition record holder Doug Howlett.
