quick question
 

hey guys. just a quick question. can i fit a 87 gt front bumper cover and 87 supermach 1 hood on a 83 glx mustang convertible? if so what extra parts would i need? any advice would help. thanks.

I think you would need everything from the front of the fenders forward. This means the grill, headlight assemblies and everything else. Best to have a donor car or access to a good junkyard.
