Hi, I have a Bradington Young manual recliner I bought close 20 years ago. A quality comfortable chair. The gas spring is worn out fro what I can see the pin is stuck in th e pushed in position which I believe releases air for the chair back to recline. Does any one if the gas spring is still available or is there another one from a different vendor that would work? Th gas spring I have is from Suspa 01850099
