Saab Body parts

Does anyone know if you can change the boot lid and rear lights of the 900 convertibles to the newer more modern 9-3 rear end. (boot & Lights & maybe the quarter panels to match)
And also if it is possible (probably isn't but anyway) to transfer the front and rear bumber bars to the different, newer style.

If anyone know anything about and body parts being transferable please tell us caus i know the grill is, and the overall shape of the later 9-3's are not all that much different to thr earlier 900's

I would never even think about contaminating an classic with an NG but if you must post your Question on this Saab sight;
