Had a bit to do with Rob and Don, This Don Halliday was mechanic at John Andrew Ford in 70s, won the BNSW championship with the NZ built Escort BDA against the Willment car. The other Don Halliday raced ( maybe built) Formula Vee here, now very respected designer?/ engineer in single seaters. Don and Rob Halliday cars built in first small shop in Sandringham before shift to Morningside. Steve Horne part of that small group.
And there is another Capri also being built, I believe for an ex saloon car , now single seater driver.
