Hi, All,
I recently put an electronic power steering unit from a Prius into my 1973 VW Squareback. It cost me less than $100, and is WAY easier than any hydraulic pump solution. Using a torque wrench to measure steering effort, the effort is about 1/5 what it was before.
I posted the whole procedure on TheSamba, a chat board for old VWs. If there is interest, I can repost it here.
Here is TheSamba link:
