Exceptions to the actual grid of the 1967 U.S.A. GP are the BRM P83 of Jackie Stewart in place of the BRM P115 and the Cooper T81/b of Ickx (which he actually used during practice), instead of the Cooper T86.
The rest (credits included) is as usual. To be noted a new steering wheel for the Ferrari 48v produced by Silence. A retrofit new version of it for Monza is also included in the download.
For the installation, copy your working MONZ67 carset made for Monza 1967 and rename it e.g. WATG67, then copy in each specific car folder the here provided files. Copy also the provided specific Watkins Glen drvc67 file in the watglen track folder and the solana pbf picture in the layout folder.
Good historical racing!
