What would I have to do to make an old vehicle who didn't use the universal wheel system be able to use it?
You have to change the wheel slot on the releated suspension in order to make the game searching on the common wheels , this is for example the Gran Marshal : ["wheel_F_5","steelwheel_03a_15x7_F", "Front Wheels", {"nodeOffset":{"x":"$trackwidth_F", "y":-1.45, "z":0.34}}], On this case , the game will propose all the 5 bolts front wheels available , and the "nodeOffset' will correctly position it on the car
