Hi. I was wondering if someone could lend me a hand, I had an unfortunate accident a where one of my headlamps came loose and ultimately fell out (the entire unit), smashed, and got ran over destroying the plastic headlamp bowl as well. I need to buy all of the parts to replace both headlamps now but I don't want to miss anything off the list. I'm guessing I need the headlamps, headlamp bowls, inner ring and outer ring. Anything else I need to get? Sorry if this is a stupid question but I'm a bit clueless when it comes to exterior parts! It's a 1990 Rover Mini Studio 2.
