BMW E12 hood torsion bars

[Rogelio]

Good afternoon, my BMW is an e12 528i, 1979 molding, I have problems with the opening of the hood, since when I pull the handle, it does not rise nor does it slide forward, the problem, I think it is the torsion rodsthat carries inside the tube that hold the hinges, I attach photos, I want to see if you can send me photos of how these rods are going, which I already bought, but I don't know how to install them.Thank you
