I read about a steering box conversion in one of the car magazines. I picked up another box off a 90 caprice which from that the magazine showed will work, just need to have the high pressure line made. Has anyone tried this conversion? If so, does it make a big difference?

A similar GM box to the 90 Impala LE/Police box
is the 1987 Grand National box. Have driven over
a dozen Chevelles with the Grand National unit,
and all have truly been transformed & improved.
