This turned out to be a great swap for me. Better and tighter steering from my jeep using a Caddy steering box. 100% bolt on for my 79 too! Later years use different hoses, flare on mine and o-ring type on later models. This box has the bigger piston I believe like the high $$$ AGR box. Got my rebuilt box from O'Rileys for $125 and it comes with a lifetime guarantee. I said 100% but I just remembered I had to grind off a little tit on the end of the steering shaft coming out of the box, no biggie. The doner turned out to be a 1976 Cadillac Coupe Deville (sp?) you know, the big boys they used to build. This is a new one on me and I just thought I would pass it along. I wish I could take credit for it but a friend of mine came up with this one looking around a junkyard and spotting an old caddy sitting in the corner. Looked like it would work so he bought it. He swapped the hoses on his 85 and bolted it on. He told me he would show me how to beef up the pump but didn't think I would need to. I kinda like having a AMC, Ford, Chevy, Scout and now Cadillac jeep!!!
