Hi all, thanks for the information. Yes it is a new (Sep 21) Plus Four with a mohair hood. It had been down for about two months. Following the problem, my dealership suggested trying to attached the hood to the rear without it attached to the windscreen. That worked. I was then able, with a little difficulty, to attach the hood to the windscreen. It was then suggested that I try attaching the hood first, but do not pull down the catches. That worked. It was also suggested that mohair hoods shrink a little if not up, so I am hoping all back to normal after a week of the hood up and stretching a bit.
