that sounds like the same place i got my angle eyes from. told them i have a PH1 and the lights i got back fit like a glove.
not sure if there was a wireing change between PH1 and PH2 lights but they are def shaped slightly differently on the inside edge that meets the grill so if you want a PH1 grill you'll need PH1 lights and vice versa.
the only grill that will go across both is the reiger grill which overlaps the lights slightly so you dont see the gap
if youre using a phase 1 grille then you just need to order phase 1 lights, or from the sounds of that site, the ones from 1991-1994. i bought some gsi headlights for my phase 2 and i was told they are a straight swap. fitting them with my gsi grille this saturday so will find out...
