Hi,
The Chassis numbers are in the form of a plate that is nailed to the floor board in front of the seat. As an example it should read something like: B1234. The "B" represents having came out of the Brisbane factory at the time. The plate is only about 2" x about 4" and is made from brass.
Unfortunatley, for every 34 Chevy I see with the chassis plate, two don't have them as over the years they just disappeared...either the timber rotted and they just simply fell out or someone took a liking to them.
Holdens also had their own body tag, which is located under the front seat base on the passenger side. These are made from aluminium and are about 1" x 1 1/2" or so. On this you'll find the body style...in your case RDSTR; Body Number, Job Number. I think also something else. Memory lapse!!
So what you should have is two plates: One brass and one Aluminium...or the holes where they had been nailed in anyway.
The 34 Std Buisness Roadster timber frame stepped up infront of the rear axle area and then continued under the steel floor in the Dickie/Rumble Seat area. Much like, if not the same as a 34 Master Sports Roadster.
The 34 Standard Sports Roadster timber frame finished infront of the rear axle with the front edge of the steel rear floor being fixed too, and timber framing inserted on the top side of the steel floor in the dickie/rumble seat area.
The 34 standard roadsters, like the sedans etc, had a ladder type chassis, where as the Masters had the x type chassis, which I think was adapted for both models for 35.
The 35 Cowl vents open at the front, where as with the 34 they opened from the back.
Grills are different to both Master & Standard in the 34 range. Not sure about the 35's?
The following link, is to a picture of my 34 Standard Sports Roadster. Have a look at the front fenders. If yours are appear to be a different shape, then you probably have a Master Roadster. Also, the Masters had a 6 stud axle, whereas the Standard had 5.
