Adrian from Civic Garage is currently gauging interest in replacement seals for the 1st gen Civic 3 door rear hatch glass.
This item is NOT available aftermarket and very few NOS are known to exist.
He will need quite a few of us to respond to his facebook post to make this feasible.

This is not spam but a genuine attempt to get a difficult to find part manufactured.
