I don't know is this a dump question, but.....
Watching that Pursuit of Le Mans video just a minute ago, there were shots from the factory (recently seen screen shots here), where was told about the carbon fibre braking system of Le Man's GTR's. There were a big sing,
GTR 036. But the car seemed to be #01R.
How the chassis numbers went that time?
First they did a roadcar, and named the chassis it afterwards again?
IF that 036 is the basic F1 roadcars chassis number and it became #01R....
How this chassis number thing went back then?
