Yes they are Eligible to race in the Nc category. But only if they are the original cars that raced in the period 1964-1972 which exactly what Mick Stupkas' Citroen is eligible to do. Mick understands that it is not competitive in the Nc, as the 115% rule would get him almost every time.
But it's not an Na car so it doesn't have to comply with Na regulations.
Rather than discussing the car and it's eligibility or otherwise here why not approach either Michael Stupka at a race meeting or talk to any Group N EO. I'm sure they are all aware of the car and can give you much more information than I am able on that specific car.
A starting point maybe to an enquiry to firstname.lastname@example.org
I feel sure that the HTCAV eligibility officer could explain the situation to you complete satisfaction.
As I have said before the Nc regulations were developed from the various sets of regulations covering "Improved Touring" and the regulations covering Cars Eligible for the "Australian touring car championship" only during the period 1964-1972. There were lots of other regulations also in the period including for 6 cylinder series and others as well. They didn't happen overnight, from memory the meetings and discussions with the CAMS and all interested state bodies went on for nearly 12 months before the first draft of the rules was published for consideration and comment. Then there were meetings to take into account all the points put forward including many from John Dawson-Damer who at the time was the chairman of the HCC under whose authority the regulations were put together before being put to the CAMS for final ratification and approval.
I fully understand that the regulations for Nc didn't exist as on homogeneous set of regulations. They were worked out from at least 6 different sets of regulations in existence during the period post Appendix J prior to Group C.
To be absolutely truthful the current Na regulations also don't have much in common with the original Appendix J regulations from the 1960's or from the regulations that were drafted to reform the Appendix J category in the early 1980's. They were also a problem as it was forgotten to include a clause that stated only cars that raced in Australia in the period were eligible. This was admitted as a fault/ oversight much later after some exotics started to race including my Prince Skyline which never raced in Australia in the period and others.
Series production was specifically left out as it was deemed impossible to build a car to the original regulations as original specification production parts are/were no longer available.
Petes' Mustang had to be built and presented in the form in which it raced in the period. The same as the Stilwells' Escort for example.
The concept for original genuine cars that competed in the period was was to select a time in the period and present the car in that format. If the format selected could be verified for example with fuel injection and a 5 speed box and 4wheel disc brakes for example at one time and it was legal at that time then it could be raced in that format in Nc but only the original car can be raced in that format. BUT it still had to be approved by the Eligibility Officer before the Log book was issued.
Na, Nb and Nc definetly aren't Historic within the strict ideals of some of the earlier categories but they are by far the best supported category at the historic race meetings but there are also gaping holes in the regulations and eligibility issues for just about ever other category in the broad umbrella of Historic Racing.
GpN is becoming less historic for many reasons. Practicality, performance, safety and at times expediency.
Though it appears that there is supposedly not enough Mustang and Chev blocks and heads left in the world! EHs finally got too use a gearbox instead of a handgrenade, humpys must use a later model diff housing and axles etc.
Plus we have cars built with modern rollcages and the like. Though the obvious stupidity of having to wear a Hans device but using a low back seat, or in a few cases still the original seat. Which until recent times was what you had to use anyway.
I used to call GpN pre 64 Sports Sedans, now pre 72!
How many basically App J cars do you see now? Is there any Valiants competing, any Lotus Cortinas, Jags??. Still a very few EHs. A few Mustangs,, that never raced in period and a few Rallysprints of which about 1 is original.
The 65-72 cars should be recreating the rules that were raced with then. Which they largely do in the US.. Our Improved production rules, at least later where similar to Trans Am.
Series Production is doable,, at least in a visual sense. Internal components for engines etc are long gone or if available one size fits all now. eg Pistons. Modern are lighter, stronger though in many cases have less compression too, by a LONG way sometimes. Though they are always available for moderate money [non forged]in standard compression height for nearly all engines
And CAMS has to look at basics too. Tyres are a problem for many cars. Too wide, too skinny and or not enough speed rating. In 2012 I saw camaros and Mussys running on tyres to narrow for the rims and speed rated 60k too little too. Currently you have two choices with those cars, Yokohama 032 which is a fairly old tyre and unless has been updated H [200k] speed rated. Or Hoosier rag tyres with no stated speed rating! And are a race tyre not a street tyre. Ooops! Personally the Yoko is the tyre too use and seem to live ok. Just very hard to source and really they do not wish to make a tyre that has very small volumes anyway! Hoosier is a specialist tyre manufacturer unlike Yokohama and can get away with smaller volumes
The other end of the scale has Minis with no choice at all except Hoosier, again a race tyre.
