Alfetta Coupe Wiper Scuttle panel

[marks alfetta]

Hi

Would anyone know a source for new old stock or good used Wiper Scuttle panel for a 1975 Alfetta GT.  I assume the GTV up to 1979 would use the same panel.  Do the later models GTV's or GTV6's have the same panel excluding the fact the slots have been cut out and replaced with a plastic insert. 

If the GTV6 panel was the same dimensions I am assuming you could weld in the slots fron the earlier GT or GTV's to make the panel the same.

Has anyone tried this does it work?

Regards

Mark
