Its just the height differences of the inner and
outer tie rods and lengths... they have you change
the heights.... once you do a toe curve you can
determine whats needed

Also being that the upper and lower control arms
are different in length and the different mounting
points(for cornering) the arc's are different so
it pulls inwards through the travel... thats why I
like a stutt suspension so much better

Aside from heating and bending.... are there other alternatives?? I know there are bumpsteer kits. Not many for Mopars... There is the Hotchkis kit. It is VERY NICE but also expensive.......

The book tells you to bend the arms on the lower ball joint..... you can use Rod ends in place of Tie rod ends now. I would like to find a way to make up this set up myself. The threads on the Mopars are 9/16 (Odd ball) so they do not lend themselves to any easy 5/8 Rod end conversion. There are no 5/8 to 9/16 sleeves availible.....

I have the manual, I have a torch with a rosebud.. I have a car I want to correct but I've never gotten comfortable with heating & bending suspension parts..... Should the parts be allowed to cool naturally or quenched? Dull red glow or bright red before bending?

Lofgren Auto Specialties makes a kit that uses the stock inner tie rod ends and 5/8" rod ends for the outters. The kit comes in two versions. One comes with a spindal stud to adapt the rod end to the lower ball joint. The other kit uses 5/8" diameter bolts to attach the rod ends to the lower ball joints (you must drill your ball joints to 5/8"). The kit with the spindal stud is $249.95. The kit with the bolts is $149.95.

if you have a friend at a machine shop or have the machines yourself then you can have adaptes made that uses your old tierod sleeves to use a high mis-alignment heim joint, then have the adapters tig welded to the sleeve's after you figure the proper length that you cut the right hand thread end off the sleeve,,I made mine with a stub that slip's into the sleeve snugly then had it welded,,, then drill your arm's for a grade 8 5/8 bolt and start making sleeves to space the heim joint to the height it takes to obtain no toe change in the full travel of the front tire,,,here's a pic of mine as I was mocking up the pieces, the hex piece on the end of the sleeve is the adapter.

You don't need an aftermarket UCA (upper control arm) to do bumpsteer.
Just because you buy a alterkion doesn't mean you can't dial in better bumpsteer. When you are adding thin shims for bump adjustment, you can't expect a kit or custom chassis to be right on out of the box.

wont work,,both ends are female thread, the 9/16 need,s to be male, but even that wont work because the combination of all the part's will make it too long.

So am I seeing this right? Just the Hotchkis upper control arms by themselves does not correct bump steer? You also need to move the outter tie rod end.

That is correct most of the time. You need to set caster/camber, then work out the bump steer. As you put more caster in it will lower the outer tie rod on a stock style front end.

speedway motors has EVERYTHING you need.
They also sell reamers if your balljoint taper for the tie rod ends is not the adequate one, you just ream them up to size.
On my 67 cuda setup Im using the lightest A Body spindles with the big upper balljoint, but the those spindles use a smaller upper ball joint, so I bought the reamer and reamed it so it accepted the bigger ball joint.
You can find the tappered pin/stud adapters, the ball joints, and the sleeves you need, as well as the nuts....and they are all super cheap. You should not have more than $150 bucks invested with all you need to buy.
Longacre also sells some bump steer gauges which should help you measure the bump steer accurately and set it all up nice and precise.

I like how Brads70 reinforce the spacer section.. just putting a spacer down there you WILL get flex and the way he did it should eliminate the flex... I have the tapered ream and I think its 8* if I remember right
