Its a brand manufacturer and probably the most well known for any platform available. They have everything from a full kit, gearbox, etc. they have steering assist, full hydro steering...
Some people have used different pieces from different places making a DIY project out of it. People have upgraded to a saginaw pump, better hydroboost units...anything is possible.
I've installed a kit on a newer ford and dodge and seen plenty of them on youtube. I can't give you specifics but you can look into it. It's not a cheap hole to go down into though, but probably the best you can get IMO
there are also alternative versions out there.
I think PSC gearboxes will allow for a standard instal or ram assist off the same gearbox, so you can upgrade later without needing to change the gearbox again. that's the route I should have went. I don't know if this was available on the redhead gearbox or not
