What is everyone doing with the massive gap left by using the S interior panels on the R chassis?

FFR didn't send me the one triangle piece for each side, but I did get the dead pedal and the coolant cover. Since the R frame is 90 degrees from the floor and doesn't come in at an angle like the S they really don't fit.
