My 2020 Roadster was specc'd. with a traditional, 9 stud, mohair hood. The hood frame is different to previous 9 stud frames that I have had in the past and the hood swivels cannot be fitted. I use the following method to fit the hood -
Fasten the hood at the rear of the car. Leave the hood frame in the horizontal position, then fasten the hood to the studs at the top of the windscreen. Sit in the car and pull the frame up from within. Then attach the side fastenings on each side.
This method works a treat on my car.
