Ka bluey, no I dont have problems like the DEPO lights you mentioned. However, there were fitting issues which was mentioned in my eariler posts.
Brad, as Ka bluey mentioned it is a clip problem. You may either remove the clip altogether or cut it down to fit our cars.
Alister, me thinks the US U13s are made in the USA. I got bits that say Nissan USA (for the stuff I buy from the US) as opposed to Nissan Japan bits as per my Aus Spec car.
Again, I dont know why, but the americans JUST have to be different. I would have thought they would share the same molds at least to save cost. Anyway, these will be my last US based mods thankfully. NO more I tells ya. The rest will be locally made. Would attempt to make a mould (custom) for the rear skirts. Will let you guys know if I am successful in it.
