Is it possible to install a duckbill spoiler off a 1986 rx7 and put it on a 1988 convertible and still be able to open the trunk and not drill holes? perhaps some type of type or adhesive? any help would be appreciated thanks!

 

the duckbill may work. you'll have to put a hole in the trunk though. and you'll need to make sure it doesn't contact the edges of the body that is not attached to the trunk
