Matt Stone Racing has received its first Gen3 chassis from PACE Innovations.
MSR will race Chevrolet Camaros when the Gen3 platform debuts next year.
The team received its chassis from PACE Innovations, one of four chassis builders, on Monday.
Brad Jones Racing took ownership of their first Gen3 chassis last month.
The BJR chassis was the first of of 16 built by PACE, which will supply a majority of the Supercars field.
Yatala-based PACE will supply complete spaceframes along with kits and materials to teams.
Triple Eight Race Engineering, Erebus Motorsport and Walkinshaw Andretti United will construct their own chassis.
Camaro panels also arrived
Erebus recently completed its first Gen3 chassis via the team's Mount Gambier-based fabricator Jimmy White.
Gen3 forms a key part of MSR’s future, with the team to run General Motors machinery next year.
The team will run two Camaros in Supercars and Commodores in Super2 and Super3.
Chassis fabrication of MSR's three Camaros will be completed by PACE Innovations.
However, MSR is finalising the assembly of its cars in-house.
Camaro panels have also landed at the team's Yatala base.
It will be the first time MSR will build new Supercars.
A render of an MSR Camaro
MSR currently races Triple Eight Commodores, and has a technical alliance with the team.
The Truck Assist-backed squad is equipped to manufacture Gen3 control parts in-house.
Given it will have three Gen3 chassis, MSR has flagged it may also field its spare for a wildcard programme.
The make-up of the team's 2023 driver line-up remains a question mark, with Todd Hazelwood linked to a move away from MSR.
Hazelwood has been linked to Blanchard Racing Team, with Jack Le Brocq expected to remain with MSR.
MSR's 2022 campaign will continue in Bathurst next weekend.
Tickets for the Repco Bathurst 1000 are available on Supercars.com and Ticketek.
