Looking for roof detail pictures of GP35R’s and a U25B

So I got a pair of Intermountain SD40-T2’s, one was missing a bell and a plow. Intermountain supplied me with a new plow as well as an entire parts sprue…so I have TWO roof bells! My 6300 will be getting more details.

Also, on early U25B’s…does anyone have a good photo of the bell location? Not many realize this, but their bell was on the frame
