Bedside patch panel

[Mike's money pit]

I have 2 places on my short fleet drivers side bedside that I need to patch. They are in front of and behind the wheel opening from the lower molding down. I have been reading up and it sounds like the repro patch panels will not work for me. I think they are missing the wheel lip which I need to replace. Does anyone have experience with these patches? I am thinking I need to find an original bedside and cut the patches I need. Any input is appreciated.
