325i and 318 what parts can I use?

Hello new guy here!!! I'm trying to research something before I desmatle this car. Ok here is the situation, I own a 93 325i and I havent driven this car for the past 2 years, it's been sitting outside on the driveway and yes the elements have damage a lot of parts!!! I had a colision and damage the left fender, hood, complete bumper, radiator. Also both front windows and sunroof are out completely, seats need to be replaced, the actual stick for shifting rear right suspension. What a mess! My friend owns a 1995 318 and his about to sell it to the junk yard, but he told me to take off what ever I need, does any one know exactly what parts can I use?? Specially the mention above?? Thanks and hope some one can help me!!!!!!!!!!!!!
