are your glides in good shape? not missing or extremely worn? if these are intact..then you could have sag due to age...did you adjust one side only to the next notch and leave the other in orig. position....may have to mix and match a bit....I would not know where to find original data for re-curve of any torsion spring..
I have adjusted up and down the slots in every conceivable way. It's either too soft or rips your face off.
Glides? I don't see no stinking glides.
What are they, where are they supposed to be, and what do they look like?
