Mustang II spindles on stock control arms

[Super73]

I am working my way towards a little more weight savings. I don't want to spend the $3,500 on a front suspension right at the moment, so I am growing in pieces.

I have a set of MII spindles and started looking at things.

CPP Drop spindle weighs 24lbs
MII spindle weighs 7lbs

Current 11.75" rotor weighs 28.8lbs with bearings and dust shield

Current caliper weighs 11lbs

My current CPP drop spindles are 8" 11/16" tall where the MII ones are 7" 5/8" tall. At my current ride height the upper control arm is slopes down towards the frame (higher at the upper ball joint) where the lower is level. The reduction in spindle height will likely flatten out this slope.

Next is ball joints. The upper looks like it might have the correct taper and enough thread to see the nut/cotter pin. But.. QA1 makes aftermarket upper/lower ball joint that are rebuildable.

They make an upper housing for our GM arms and a MII taper in standard length +.1" +.5" +1" ball joints.

Part numbers for upper:
1210-101 = Standard height
1210-201B = +.5"
1210-238B = +1"

The lower needs to be done in 2 pieces as they don't sell a complete unit.
Press in housing for our arms 1210-510
Ball Joint for lower MII that fits that housing is 9029-229

The next thing that will need to be addressed is the steering linkage as the MII is a bottom tie rod feed where the truck is a top tie rod feed. I am going to drill the spindle square and run a rod end. This may require me making some form of threaded rod to accommodate the current adjuster.
