The Saginaw is a way superior setup. The federals are not as good.
You just need to get the right brackets, and pressure hose. The hose you can buy at NAPA.
I switched from federal to saginaw on my dart. It has the stock k-frame and does not have A/C. Bolted in as long as I had the saginaw brackets and pressure hose.
Here's the hose routing in my dart. and what a loose setup looks like (sorry bad pic)
