Graham, my ask is that you consider adding the 69 Camaro, Porsche 934 back in please. I’ve I just received a ton of parts and even opened a Porsche that’s been sitting since April ‘2021 and started building cars, I assume others may have started doing the same. 

On the wheels, I assume you are measuring at the rib and not the face as I’ve seen this complicate building in the past.  I suggest a simple 15x6 to 15x10 minimum size rule.  Unless the vehicle was equipped with a smaller diameter wheel. 

Just a comment regarding B&W chassis, if there are 10 cars with B&W chassis maybe consider it as a class on its own without a body restriction as with mounts the bodies are as heavy as other bodies.

I have restored the Porsche 934 & Camaro 69 to the list for you 

In the past you could have said that the "Richard Mack chassis " were commercially available, but sadly Richard does not seem to sell them anymore.

Sorry but Not being very familiar with the Porsche 934, I checked it out this morning, and like the Porsche 911 RSR it has quite wide wheel arches compared to the other cars in this Category. So I think it is out of context of the other earlier cars in the " Monte Carlo -Sports car" category, and have moved it across to the "Tour de France - Touring Cars Category. It's now in the same list as the Camaro 69.
