Hello,
Some feedback from CPP stated " I'm sorry the power steering kits we
offer are designed to fit half ton models only" this is in relation to the 500 series steering box they offer.
Have only briefly reviewed TRW electronic assist, i don't know what it is but i would like to keep it mechanical, it doesn't seem to sit with my idea of this era truck or maybe it is just fear of something i have little experience with

Gentrysgarage, looking forward to hearing about it

Cheers
