Can somebody please tell me how difficult it is to upgrade the boot, bonnet and bumpers on a B5 pre-facelift model to a facelift model. I have not been able to find a thread or webpage that describes how easy or difficult this is to do. I have seen a facelift model with these parts in excellent condition as salvage and I am considering fitting them to my own pre-facelift model if it is easy to do so. Any help or advice would be greatly appreciated.

Thanks
