89 gta front struts

i have an 89 350 gta ws6 suspension(long i know) but i need new front struts but i loved the way it handled when it was new (my dad had it, but i bought it) i figured i would go oem, i tried gm parts direct.com but does anyone know if there standard or heavy duty struts. i think standard would be the same as the other firbirds though. anyone know? thanks
