I think you're confusing two different cars. The 'Rampo Yanaka' car you posted a photo of up-thread is not the car which was refused an entry to the LMC some years back.
No disrespect to Rampo, but his car is a decidedly home-built, road registered car inspired by the look of the original '75 Le Mans entry and little more than that. I've seen it in the metal in Japan and, whilst it looks the part from a distance, it doesn't cut it close-up and is decidedly rough around the edges. Enough said.
The car refused on paper by P.A. was a pro-built race car, largely *correct* in detail to the original '75 LM entry, including the E4621 FIA-headed LR24 engine, ECGI fuel system, 120 litre trunk-fill tank, works KS wheels, N3020-kit body parts and all sorts of other stuff. At the time it was single colour, unstickered/liveried. After it was refused, the project changed direction and is now quite different. And it was more than 10 years ago.
