my boyfriend has fitted astra mk4 lights into his corsa and i know that headlight conversions have a lot of work involved. he needed modded wings, inner wings, bonnet, bumper, radiator, wires, fuebox and relays, slam panel, crash bar and front panel he wants to fit mk4 lights on my mk3 once it looks a little less standard donna x
In short yes you can fit original Mk4 headlights to a Mk3 golf see this link. http://www.pocketrocket.ca/mkiv_headlights.html Buying Mk4 looking lights would be easier though!
