my neighbor has a g2 integ with the type r front lights. looks pretty tight, i'd prolly reather do that than get a whole new front end. don't know about body work. i'm sure there's some cutting and bondoing (is that a word?) as stated earlier

 

I know a Jetta isn't a Teg, but my friend put Euro spec conversion on his Jetta and being in the collision business, I told him he needed to change the radiator support. To make things short, It looked like ass under the hood. We cut things and rigged things up to make it work.

So if you value the factory look underhood, don't do it. I'm sure it's not a direct bolt in. It won't be worth it in the long run. Sorry to disappoint you if I did, but I hope you will realize this.

And I don't believe bondoing is the proper phrase. Try "body filler" to be more politically correct.
