Here is a good shot of the floor cutouts required to clear the chassis rails. The forward trimmed portion only effects the rear foot well pan to where it rises and meets the seat base. The rear cutout is the very rear of the rear seat pan.
In order to design the chassis to accept mini tubs and up to a 345 series rear tire. The frame rails had to be brought in slightly. In doing so we have found on most cars we have done here with the factory trunk pan, that you will need to relieve the front side and corner of the suitcase well to allow for clearance. There are many ways of doing this small detail from a dead blow hammer to how we prefer to do it
. We start with two cuts. The vertical cut starting where the bottom of where the pan contours up and the horizontal cut at the top transition of the pan effectively creating a "T".
Now we can join the body and chassis together for our prefit. This is where you want to double check your clearances and take measurements to make your and fit your floor cover pieces.
