How difficult is this?

[k5bucket_o_rust]

I was wondering from people out there who have converted from manual steering to power steering how hard is the conversion. My 72 blazer is hard to steer from a stop with those 33" tires and I was wondering if adding power steering would be a real diffcult task. Also do they sell a conversion kit that makes this process easier then locating indivdual parts?

Thanks, Rick
