I'd say they will be different as the 2 door quarter panels will include some of the C pillars. However, I suspect in a pinch hardtop quarters can be used on a convertible.
The outside is likely the same, the convertible inside has the bracing and brackets for the convertible top cylinders, etc. The area outside the side glass- where the moulding is may be different, check that.

several years ago I was in a shop who were cutting out the sail panel area of htp panels for install on a '69 Cutlass convertible. This leaves the panel short at the top that must be fabricated and added to the panel.
