Joking apart, if you look at AppK, there is a category called 'historic specials' that surely covers Modsports cars, so no reason why one shouldn't have HTP? As long as it is presented in period configuration, which is up to owner / applicant to prove. What that HTP doesn't do is allow that car to run against those from other categories- unless the race organiser deems it OK. Having said that, I can't see why you would want an expensive HTP on a Modsports car, as those that are racing now are doing so away from FIA interference!
