Patching above windshield ??

[jrusher]

Hey guys I just sand blasted my 66 cab and found some rot on the inner panel above the windshield pinch weld. Wasn’t expecting that least rest of cab and floor is really solid . The eyebrow is solid on the outside. I’m not sure which is the best way to go about patching this area ? Should I go right across and cut out one longer piece out or should I just cut out the three areas I have marked out ? Also i didn’t really want to remove the roof skin so I wouldn’t be able to hammer and dolly the welds . Is it still possible to weld this patch in without planishing from the back side and still have good results as far as warpage goes ?
I’ve only done floor patches, inner/ outer rockers, a pillars , kick panels and cab corners in my other two trucks but nothing really like this area where it will be really easy to see if not done right . I bought the inner patch panel other day it’s nice they offer that now . I’m going to start all metal work once winter gets here .
Thanks for any tips
