HeadlessBlue..got a large sheet of 4mm self adhesive neoprene for £10 on ebay...lots of use on a Morgan to eliminate draughts.
When I get the side screens modified ( next month?) I will try water tests...used to leaks so not the end of the world if there are afew dribbles..every Morgan enthusiast carries a towel in the cockpit !!!!
BertR...The hardtop has a quality deep headlining so it will be interesting to see what happens...many cars I have driven with fiberglass/unlined hardtops can give a drumming noise...I have a side exhaust near my right ear so maybe that will drown out any other noises !
