Rear shocks on a 1936 fordor

[billybronco1]

Hey guys, I wanted to replace the shock links on the rear of my 36 because they where shot and thought it would quiet down some of the noises in the rear of the car. Well it seems the shocks do nothing other than squeak when I push the arm up and down, no resistance. Other than replacing the shock which are too expensive is there any maintenance or rebuild options on these original shocks? Any other options?
