350 SD conversion to a 1984 300SD powerplant

[ottomann]

I have a complete 300SD donor car with a really ugly body. I am considering purchasing a 350SD with a (shocker) blown motor. I believe that it can be done with the donor car that I have. It is currently one of my drivers. The 350SD has an immaculate body. The 300SD has a solid drivetrain but a worn suspension and, as I mentioned before, an ugly body. I believe the vehicle has over 400,000 miles on it. (odo died at about 330,000 before I got it and I have owned it for two years) Given the fact that they are both 126 can I take the parts needed from the 300SD to the 350SD as I go? I appreciate all constructive replies. Thanks.
