replacing old prefab garage metal gutter fittings

Hi, I have an old prefab concrete garage, with a semi corrugated roof, possibly made of asbestos.

The original guttering was metal and held in place by metal brackets which were curved under the gutter and held in place by the bolts that also held the roof section on. Most of this has all long since rusted away.

my problem is I'd like to put new gutters on, but the prefab concrete sections are impenetrable. This things are really strong, my hammer drill with a new masonry bit doesn't even leave a scratch, so modern conventional plastic gutter brackets would not seem a viable option as they require screwing onto a vertical surface. has anyone seen or improvised a solution of this kind of thing ? I guess some kind of metal bracket which would slide between the wall and roof

Good excuse to buy an SDS drill.

I used to drill that stuff without even hammer action. IIRC I used an ordinary HSS twist drill, without hammer. Bits probably wont last long of course.
