I don't think that is possible Jennie at least for HJ-HZ as Pagewood never built van bodies. They built their own HQ van bodies, but the HJ-HZ bodies came complete from Elizabeth, painted and hard-trimmed and never went into the Pagewood BAP, they went straight to the VAP. Pagewood did build their own ute bodies for all of HQ-HZ though.
What he might mean is dented utes were finished off on the van line, but this would only be in the VAP.
