What year Road Runner?

70-75 shows same tie rod as the Challenger.

Generally speaking, the taper/diameter of the stud is the same, but the design of the tie rod is different. I ran a set of 79 Cordoba spindles on my 64 300 and the 300's tie rod stud fit fine.

As for the hose, the Aspen/Volare hose is long and what i use for these swaps, but I never did a B body. There is a bracket that needs removing though.

Of course you could just look at Mopar Actions disc swap guide for your answers.
