5.0 Mustang just did a 5 lug swap using the 94-95 spindles. They put two 5/8" hardened washers on the ball joint and then slid the spindle on. This helped keep the wheels straight. The bottom of the 87-93 spindles are larger than the 94-95, that is why you must space them up. The X2 ball joints are for lowered vehicles I think...right? Is your car lowered? I am gonna do this swap myself, use the washers on each side and still get an alignment.
X2 balljoints don't require a .330" spacer since they are already higher than the SN95 and fox. (X2 on left, stock on right)

From Steeda's site:
When a Mustang is lowered, the front roll center changes due to the new
position of the
suspension pivot points. Lower the car too much and the
front roll center drops to well below ground level, and worse than that,
the roll center moves side to side as the body rolls, resulting in lost grip
and erratic handling. The lower roll center causes the body to roll more
easily. Countering this tendency usually requires a significant increase in
front spring rate to simply control the added roll due to the lowered the roll
center. This higher spring rate not only hurts ride quality, but it also
reduces grip on rough surfaces, as the stiffer springs cause the tire to skip
over bumps instead of following the contours of the road. The X2 balljoint
was designed to eliminate these problems by correcting the front roll
center geometry. The X2 balljoint has a longer shaft, to raise the spindle
relative to the balljoint pivot point. Spacers for the springs are included in
the X2 kit to maintain the same ride height as a stock balljoint, but with
a much improved roll center height. With the roll center restored to the
proper height, smaller front swaybars and softer springs can be used.
The result is a
suspension that works for you to accommodate the small
and large imperfections that are in any road or track, allowing the tires to
stay planted on the ground where they belong.
