I own a 1992 volvo 240 polar and recently really got into the look of older 240 DL's with the round headlights and the chrome trim and was wondering whether it is all plug and play (especially with the trim) or if I would need to make some special modifications to install these parts on my newer model 240.

 

The square lights are pre 1986 and there was a major redesign around that time so it'd be difficult if not impossible.
