just need some input on how easy it is to install ss headlights into a VZ?
VERY easy. Check the sticky thread at the top of this forum. It's 3 bolts and a plug from there.
Simple:
1. Remove bumper as per instructions at top of thread
2. undo 3 bolts holding headlight in
3. undo white clip at rear of headlight.
4. new ones will clip and bolt straight in
