Hi, thanks for the responses !
It sounds a bit funny this but its not actually for a cougar !!
I have a 1995 Lotus Elan, most of the roof seals and door seals are now obsolete. Ingenious owners have been trying to find door/roof/bonnet seals off other cars and adapting them to fit !!
The nearest contender for the front hood seal seems to be a Cougar door seal at the minute. Therefore it doesn't matter which side its from.
Cheers,
Simon
