hi guys i need a little help on refurbishing my 85 735i ive got some questions my passenger front door is out of alignment a little, would that cause water to leak in? the water leaking in has made the insulation under the carpet smelly and wet, can i just replace the insulation on the passenger side or do i have to do both sides? might have more questions as i look at the car further.... (ps i already own this car)
