leave body side molding or remove it?

guys, this is an interesting discussion. Ive been trying to find the true story of my 69 340 swinger stripe delete. My car is optioned with (correct me if im wrong i dont have my paperwork with me) A46 moulding package and A05 protection group and V88 stripe delete. Niether of these packages state body side moulding. i think body side moulding has its own code. I bought my car with the holes drilled in the sides and the god awful squared off aluminum molding with the plastic inserts included. Some body side molding looks good, but this moulding i have does not look like a factory option. i did not look at the fasteners to see if they were mopar parts, i think they are metal(?) could you even get a 340 swinger with side molding?

I'll describe the type I was referring to in a little more depth. The aluminum part was kind of a channel and had holes in it to fasten it on with 1/8" pop rivets or small screws. When you put the insert in it, it resembled the factory look of the stick on vinyl moulding with the chrome edges and vinyl insert (like a '72-up a body). You could get about 4 different types of end caps. These were made of chromed pot metal of some sort. There was a pointed one which went at the front of the front fender. At the back of the fender you used a squared off end cap if the door opened inside the fender. If the door came over the outside of the fender when it opened you had a tapered cap to use so the door wouldn't catch it. So you used either a tapered or blunt cap on the front of the door depending which way the door hinged, inside or outside of the fender. You used a squared off cap at the rear of the door and one at the front of the quarter. Then you used another pointed one at the rear of the quarter to finish it off. The vinyl insert was available in several different colors. The most popular width was approximately the same as the glue-on factory moulding on '72-up a-bodies (as well as other brands), but I have seen a deluxe style about twice as wide.
Hope this explains the aftermarket type a little more clearly.
