updating 89 300e

[Jettpilot]

I've searched the archives and came across a couple of w124 owners who have updated their cars to include the lower body cladding that came on the later 124's. I have an 89 and would like to do this project as well then have the cladding painted the same color as the rest of the car. Is it just a matter of swapping out my upper and lower trim pieces with the newer cladding? Or do the clips have to be changed as well. Also can the lower portion thats mounted to the body be swapped out as well (the section that includes the openings for the jack locations).

I have enclosed pics of the setup I have and what I am looking to modify to:

Thanks for your help!
