Do u mean pop up head lights

yes the headlight that goes up and down when you open and close them...

Its possible with a welder and sheetmetal skills, they could be installed.

The problem is there...its a stupid idea but unfortunatly i have the sheetmetal skilk as i done one year of school about body work i dont remember the name of it in english but i would be able to modify the hood for it and i have acces to a welder but i wonder if there is enought place for it since i would have to take the original headlight to make some room but would need a facade...its a terrible idea but if my friend send is 1g to scrapyard i will strip the pop up light and frankenstein my 2g with it...it will be so unique juste like me and my crazyness mwahahahaha

With enough money you can do just about anything, but honestly if you are dead set on it, I think you are better off either just buying a 1g(or maybe trading for 1) Or if you want the curves of a 2g, it'd probably be easier to graft the body panels of a 2g onto a 1g than convert a 2g to popups. Alternatively I think what you might really want would be one of these , or maybe the some pieces from the front end of one, would probably go with the 2g curvy body style better.
