Tadpole One

Hello all, New to this site and was looking to gather information for my project. I have a 1940 Buick 8 320 in the garage in pieces. Looking to complete rebuild from ground up. What I am looking for to begin with is the information relative to the missing VIN plates for vehicle ID. The car was built in Australia with the Motor No 3812490 and Chassis No 13599401 From the manual the car is a 60 series with the Flint body built in Australia by Holden in Adelaide. It has the split rear window. The car appears to be a cream/grey colour on the firewall and I assume it was this colour for the vehicle. I have found the paint codes and trying to put together now. The motor is a lighter blue grey with age so not sure if this was in the colour code but similar to Bandelier Blue or yosemite grey. I am trying to gather as much information relative to the VIN for originality. The trim is red. I am also looking for inner guards, they are 4in longer than the 40 series. With this information I should be able to generate a code I believe. Just need to originals from looking at other vehicles I see: 1940 MOD 51 - Style No 40?? Body No ???? Trim No ???? Red seats and doors, light roof Paint No ???? Grey fire wall, internals Any assistance would be invaluable. Thanks Terry
