I dont know what ones your looking at, i dont feel like reading this entire post. you want SPC ball joints for a 95-99 Eclipse/Talon.

Here is a run down of the options available from SPC:

Adjustable ball joint style:
SPC-67170 adjustable from 0 to +1.5 degrees

SPC-67370 adj from +1.5 to 3.0 degree

Bushing style or mount style:
SPC-87460 adj from -.75 to +.75 degrees (these replace the bushing in the factory control arm mounts)

SPC-87580 adj from 0 to 1.5 degree (these replace the entire anchor bolts)

SPC-87590 adj from +1.75 to 3.25 degrees (these replace the entire anchor bolts)

These are SPC part numbers and are for front only. You will need to know how far your car is out of spec to choose the correct set.
