Outer Limits 4x4 Board

Hi all,

My otherwise very sweet 60 has shown it's first bubble in the roof gutter .

Does anyone have a photo or diagram of the cross-sectional area of the gutter so I know where to apply the angle grinder on my 3yo bright red paint ?

Have been through all my conversion photos and the only one I have which shows a sectional view through the gutter might not be what your after but here it is anyway

Thanks heaps. That's the kind of thing I'm after. I assume this view is looking at the LH side gutter, from the left rear corner of the vehicle ?
