I have a 90 gt mustang with the wildrides s box kit. Wich is the upper and lower torque boxes. I have adjustable uppers and lower control arms. The control arms are at the stock bolt hole location and stock length. Well my car is giving me a little vibration. I checked pinion angle and comes to .5 degrees. I have stock bushings on the housing and upr control arms wich are helm joint uppers and poly and helm joint lowers. Can anyone tell me what the other bolt holes do?
