Hi , I need some help , in middle of swapping from front drums to disc brakes on my Runner , used 73 challenger spindles rotors , calipers , cant get brake hoses for a challenger to work and my tie rod end seems not right wont tighten up in taper any suggestions would be greatly appreciated

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.

its a 70 runner , thanks for the reply

Well, looks like something else is wrong because a 70 Runner and a 73 Challenger use the same tie rod end, only looked at the outers but that's what connects to the spindle.

Here's the link to the MA swap guide http://www.moparaction.com/Tech/archive/disc-main.html

If you front hang the calipers then the E-body hoses should work okay. The tie rods are the same so there shouldn't be any issue there.

Should be a basis bolt in swap. B-body and E-body front suspension setups are very similiar for those years.

Just to verify, you put the tie rod in from the bottom on the spindle side and from the top on the inboard side?

Yes thats the way they are installed , thanks for the suggestion

Thanks for the link to the MA article , think I see my prob have the calipers mounted on the rear instead of the front

You can make it work with the caliper to the rear but you need late model calipers and different hoses.

Since you have a '70 model there is no reason to run the calipers to the rear. You'll have plenty of anti-sway bar clearance with the in-board mounts so just swap the knuckles side to side and everything should go together for you.

I recommend up grading to the 11.75 rotors while you have it apart. Just buy the taller caliper adapters from DoctorDiff and slide on the bigger rotors. You'll need 15 inch wheels but most cars would have those by now anyway.
