MOD 1979 caixa de marchas

Hello, I have the 1979 mod and I run with a 6-speed gearbox, but the PC cars run with the 7-speed gearbox, both are wrong, the 1979 season was a 5-speed gearbox, it is possible to change the number of gears in the mod ??? (Google traslate)

yep, you can change it in the performance files of the mod
