Hi all and many thanks for your replies, most helpful. The welcome to the forum means a lot.
Not sure I have the confidence to "DIY", although I did just strip and rebuild my seats so I'd value your comments on whether recovering the sunroof is easier or harder than that job.
Rugbyref1: Many thanks for the photo. It could be my imagination, bit the distance between the rear screen rubber and the rear edge of the sunroof on ACG5 looks greater than on RJW307R (my car), but I'll measure up. Could it be that there were different 3/4 lengths?
Chris - I have sent you a PM.
Finally, has anyone used http://www.littleportboathaven.co.uk/br ... unroof.htm
and if so what are your reports?
