Watch it "Doc" the bolt threads on our older 350SLs have some 14 years on Larrys 86' 560! The threads can be soaked in penetrate oil for a week and still snap, they are located inside wheel eyebrow lip, 99 out of 100 snap, unless they are brand new or "mint" Your best option is just figure on replacing these mouldings. Judging your pictures and money spent on your 350 whats another 2 or 3 hundred! Start with the small piece on front fender for practice they are easy! Also i should tell you that before you just start prying them off (after you snap one small bolt per trim) be careful at the other end is a "plastic slide" on every piece. On door moulding look on the door trim just under the weatherstrip on our 350's there is a screw to remove, then you take the palm of your hand and bump the trim towards the front fender. In order to pop the plastic nibs about the size of a pencil eraser (pictures to follow) I like to use a thin paint spackle knife in combination with some plastic bondo applicators
Pull out with your hand first add plastic bondo applicator second so as not to mar paint and third pry with spackle knife as close to the plastic nib as possible and presto!
On the rocker chrome there is a phillips screw on the front fender side and another bolt attached to a rocker clip at the other that will also snap in half unless it is really new! When you put this trim back on you should almost always use new 'berries" (red plastic clip holders)
Hope you have more luck than I Doc my pieces were shot in every way.
