Just five driving combinations are yet to be confirmed for this year's Repco Bathurst 1000.
The Shell V-Power Racing Team confirmed Alex Davison will partner brother Will in the team's #17 Ford Mustang.
The reunion of the Davison brothers coincided with the news Scott McLaughlin will not feature in this year's race.
United States-based McLaughlin, the 2019 Bathurst winner, was slated to drive for the team.
However, the effects of the COVID-19 pandemic have waylaid his chances of making a 10th straight Bathurst start in December.

The champion Ford team also confirmed Tony D'Alberto will share the #11 Mustang with Anton De Pasquale.
Tickford Racing has yet to assign James Moffat, Thomas Randle and Alex Premat to their Bathurst drives.
Matt Stone Racing, meanwhile, has yet to announce its co-drivers for Jake Kostecki and Zane Goddard - but Jayden Ojeda completed an evalutation with the team last month.
Team Sydney was the most recent team to confirm its driver line-up, with Jonathon Webb and Dylan O'Keeffe to drive with Fabian Coulthard and Garry Jacobson respectively.
A six-day Repco Bathurst 1000 will round out the 2021 Repco Supercars Championship season.
