Erebus Motorsport is nearing completion of preparing a spare chassis for Will Brown for the next round at Sandown.
Brown's maiden full-time appearance for the team got off to a rocky start following a Practice 1 crash in Bathurst.
The 22-year-old crashed heavily exiting the Dipper in the first session of the Repco Mt Panorama 500 weekend.
He recovered to finish both races, but it came after his team worked overtime on the Friday night to return the #9 WD-40 entry to the track on Saturday.
The team has returned the damaged chassis to its Melbourne base, and has transferred race-ready components to the replacement chassis.
"We worked basically all night Friday night to cut this whole corner off," Erebus CEO Barry Ryan told Supercars.com.
"Some repairs on the chassis rail that we had to straighten out.
"Essentially, the whole chassis rail twisted over and went back about 8mm.
"We repaired it as good as we could at the track, but now this chassis needs to be put on the jig properly.
"With the timeframe we've got, it's best we use the spare chassis and convert everything out of this into the spare chassis."
With three weeks between the Bathurst and Sandown events, Erebus opted to revert Brown to the team's spare chassis.
In an ironic twist, the chassis which Brown will use also required an overnight fix from Erebus following an accident for Luke Youlden at the 2019 Bathurst 1000.
Despite the quick turnaround, Ryan was confident his team will have a race-ready car completed and prepared for Brown's maiden full-time hit out at Sandown.
"Some parts were already in the spare chassis, like the wiring loom and bits and pieces," he said.
"All the parts will be taken out of that and transferred into this chassis, which is identical.
"This was the chassis that Luke Youlden crashed at Bathurst, which we did an overnighter on, ironically.
"For only arriving back at the workshop yesterday, it's already come along really good.
"This could be ready to race this weekend if we really needed to. Luckily we've got a week-and-a-half more.
"It'll be a perfect car, ready to go straight out the gate, and hopefully put it on pole."
The Repco Supercars Championship field will return to Victoria for the Penrite Oil Sandown SuperSprint across March 20-21. Tickets are on sale now.
The event will be broadcast live on Foxtel and will be streamed on Kayo. Check out the full TV schedule here.
