If you eant the best quality stick with oem but they are pricey...about $450 each iirc.
The empi's are the best of the aftermarket. Good quality but not as good as oem. The empi's can be found for under $80 each on-line (I paid $79 on amazon). The empi part is actually a trooper part#. If you search the site the part# has been opated by me and several others.
