Better add HRDC Touring Greats and 'Allstars' to the list, and Masters Pre-66 Touring cars where you will get Galaxies, Mustangs and Falcons as well as smaller stuff. Think you need to sort pads to fit American Iron as they are very popular, heavy, and if in FIA trim running drums on the back! BTW thought early Mustang was same as Falcon?
If you are looking at Historic Meetings in UK, after the obvious Goodwood Revival come Silverstone Classic, Donington Historic Festival, Oulton Park Gold Cup, Brands Hatch Superprix and BH Masters Festival, Snetterton Autosport 3hrs.......
