are the pillow mounts nessary for the ha's to fit properly. will my alignment be off until i get some pillow mounts. thanks

 

The Pillow Mounts are not necessery for installing the TEIN type HA. It is recommanded to use new pillow mounts since the original factory equiped mounts often gets old and deteriorates.
When changing out the pillow mount to the TEIN's pillow mount in the future, it is advisable that you should check for the alignment again.
