Here are two cars from the Gelo / Polifac racing team.
This one raced in the 1,000km of Nurburgring 1974. Driven by John Fitzpatrick and Jurgen Barth.
This is an earlier variation Driven by John Fitzpatrick and Mike Amalfitano.
Note: You can also place the two windshield files from either of these cars into the default "01_racing_red" skin folder, since that one is supposed to be the Georg Loos / Gelo Racing variation.
