As for the Caliper Mounting location, I know where you're going w/ that. My answer is that they're on the front. However, I've never had any issues of bump-steer or other geometry problems. Maybe I'd notice a difference if they were on the rear, I dunno. FWIW things work great as they are.
The calipers mounted to the front are the reason you have the problem you do , the original disc setup for a 67-72 A body has the calipers mounted to the rear. the spindles mounted with calipers to the front or the rear will not cause a bump steer issue or any other issues with alignment , that I have ever seen posted .
Looks like you found the simple fix thanks to Jim.

I'm not going to get into a pissing match about whether the short links work or not HOWEVER they will create an altogether different problem ...
The torsion bar and LCA have two different pivot points and both have fixed lengths. The problem with the short link is that when the suspension moves through its normal arc of travel the torsion bar and LCA are fighting each other. The torsion bar wants to pull the LCA forward and the LCA will want to pull the torsion bar inward. The long link allows both the torsion bar and the LCA to move in their designed arcs with no interference from each other.
Well, you could at least call the parts by their correct names (it's not a torsion bar, it's a strut rod)......
We've driven many miles (three cars and probably 50,000 miles) and autocrossed with a similar setup without issue. All cars have plenty of suspension travel.

No, its a swaybar, not a strut rod !
Because of the position and the way the strut rod is mounted at the front, its arc of travel does not affect the LCA's travel. Not so with the swaybar.
Anyhow, its your car, I've made my point.

Sure, here you go. 15 inch rotor, 6 piston caliper and this setup goes lock to lock without any interference issues.

Anyway, maybe I should have these mounted on the rear, but I am trying to remember if my parts actually gave me that option.
You just switch the knuckles from side to side.
AS for the shorter link method, I have done that many times too. Easy, cheap, and works well. No brainer at all. Never seen a negative side effect. The difference int he arc is minimal, and it's still all held together with rubber, so there is give.

Nice pic Andy. What size wheel does this require?

Until Andy chimes in..
I would guess at 20", perhaps 19" as well.
An 18" aluminum outer is 16.225" ID, so that gets abit tight, depending on how thick the caliper is over the edge (diameter) of the rotor

Now that's what I'm talkin' 'bout! But for my purposes, I think all I need is a short link. I only need a $20 solution...not a $2000 one.
For the next one I do, I'll put the calipers rearward.
