So, I'm thinking as much as I like the look of the qaud rectangular headlamps, I would really like to change them out. Since I saw a 240 on craigslist a while back, I noticed it had the quad round headlamps and thought it was rather neat looking. I gave it some more thought and am going to change them out. Only real question(s) I have is that when I remove the bezel and take out the back plate that holds the light cluster to the car will I be able to just screw the other "new" back plate/set of round lights back in it's place with out any trouble? Can I assume that the bezels will be the same size as the other ones? Last question - Will the wires that plug into the back of the rectangular lights be compatible with the round ones or will I need to take the wiring harness for the lights from the donor car too?

Any help would be nice. Please and thank you.
