Sorry mate, you need a set of coupe doors from a US built 1966-1970 Falcon to convert that to a proper convertible. BTW, the doors are dirt cheap but the shipping is a bitch.
I think you actually need US 1966-67 Fairlane 2-Door Hardtop or Convertible doors,as they are pillarless.Here is an example of an XY Convertible that seems to have done this.The picture is from the Falcon GT Club Website...I hope they don't mind?
