I'm running a power steering box, manual center link, Shelby quick steering arm, roller idler, StreetorTrack.com's heim joint strut rods, ORP's upper A-arms (road race model), OPR's roller spring perches, KYB gas shocks.

Just had alignment set to this:

Driver's side: -2.5 deg camber, +2.5 deg caster
Pass side: -2 deg camber, +2.5 deg caster
1/8" toe IN

This is working almost perfect on the big track at Willow Springs. I need another 1/2 deg of neg camber on the driver's side (turn 2 really works that left front tire).

On the shopping list:

ORP's lower control arms
Install the ORP 700#/inch springs in front
Koni shocks

Well the saying goes...
How much do you want to spend?
In the big picture will it make a difference?

I see a lot of you all are running PS boxes. I'm assuming they have a better ratio?

"Manual box is 19:1 while the power box is 16:1"

Not exactly true!

There are some that can be PS or non-PS with the 16:1 ratio.

Mine SMB-K box is for either PS or non-PS and it is a 16:1.

Someone brought up a question earlier that I just thought of.

Can a rollerbearing idler arm be used with a quick-steer pitman arm? and does any sell the quick-steer pitman alone?

IIRC, the idler arm and the pitman arm have to be the same length to maintain correct geometry. With a quick steer pitman arm (longer, a la the 65 Shelby), you need the matched length (longer) idler. You can, however, make this a roller, too. Maybe Opentracker would know for sure?

I have all new steering parts; added the quick steer kit with the Flaming River 16:1 manual box. The steering was very crisp, but just a tad too hard at slow speeds. I changed the idler arm to roller bearing and it made a noticeable difference at slow speeds.

I didn't change the idler arm, just modified it with the bearings.

I believe the Shelby quick steering arm can be purchased at Mustangs Plus.

The quick steering arm is on the steering box. The idler arm does not change (that's where the roller bearing goes).

Also, a point of order, having the proper adjustment of your steering box (cleaning out the grease, adding fresh grease and adjusting the steering box properly) is paramount to proper steering from a recirculating ball steering setup.

Only reason I see for me to replace the steering box is to remove the death spear shaft on my steering box with a collapsable style....

Maybe I'm not understanding you correctly, but both the pitman arm and idler arm are different (=longer). Many vendors sell them.

I use them in combination with a properly rebuilt/adjusted and lubricated (which makes all the difference) 16:1 box and a roller bearing in the idler arm.

The steering precision, effort and ratio are all very decent now. I wouldn't say it feels like a modern car or anything, but it's a lot better than before the rebuild and modifications.
