The Hydra-pneumatic front strut system on my '71 911E (targa) is worn out and I am researching my options in replacing them. The original owner added torsion bars, but didn't change out the worn out self-leveling struts.

What traditional struts should I replace them with? What is the best, reasonably-priced solution? This is a street car -- so I'm looking for a nice-handling, comfortable suspension.

Thank you for your help!
