65 spit fire fenders help!!

[cyeager@sprynet.com]

Dear List,
       I'm about to replace the rear fenders on my MK II Spit fire.
Any thing I should be aware of before tackling this project, I have
already replaced the inner sill, strengthner, and rocker panels.
I had thought that the rear fenders were in good shape till I started
preparing the car for painting and started to find filler, A little to
much for my liking so it's time for new fenders. Any help would be 
appreciated. Really I would be greatful!!

                                    Thanks,
                                    Craig Yeager
