The springs you mentioned, part # RS16933RH and part # RS16933LH are designed for use on an existing door hinge that uses a 1-1/2 diameter rod or pipe as a hinge pin.

These are made of steel alloy and provide 90 degrees of deflection. I have attached a product review video for this ramp spring you can check out.
