I have a 79 GMC K20, the guide rods are attached to an "L" shaped bracket that drops below the frame (both sides) I have seen others, IIRC they attach at one of the holes in your lower frame rail ( there are three holes visible in your pic, my guess would be the rear one). You may be able to see a witness mark where the old guide rod was.
