The bodies are trimmed - on the outsides to get the driver closer to the car, and on the far side on the passenger one to clear some heater components.
I'm also going to trim the bottom end of the driver's horn so that I can get some better access to the brake and gas pedals....right now heel/toeing is damn near impossible. I'll probably take about 1" off the bottom from the exit of the mouth toward the center of the car
