I have an 80th with the same hood. My retailer walked me through the below for putting it on.

1. Fasten the hood to the windscreen first. This ensure there is absolutely zero strain on the windscreen
2. Fasten the inner lift dots at the rear along the back
3. Pull up the frame to raise the top and get this into the place along the seams of the top
4. Start snapping the rear outer part of the top to the body
5. Fasten the twist fasteners (name?) on the side and the one snap before the door.


The key thing is to avoid pulling on the windscreen.

To remove I do the steps above in the reverse order.

Welcome to the world of Morgan and an 80th at that!
