You need to hold in position and carefully drill the chassis tubes and tap to m5 to allow the diffuser to be bolted into position.
The front edge of the diffuser is bolted up through the rear of the floor pans both sides, two 35mm spacers are needed (not supplied) also under the rear chassis cross brace tube this is so the diffuser and floor can be all the same height.

Slots each side will be needed to clear A frame wishbones in full droop.
The chassis is 745mm long from the rear edge of the floor, this part is 835mm long approx, 430mm to the fold, then 405mm to the rear so it will stick out 75mm at the rear approx
