I love the way your models come out. I have one more 65 in my stash, which is a hardtop, which is in the same shape as the one you have. I have another '65 hardtop built, which I did not photograph. I may go down in the display and get it out to photograph.
The one I am going to build may get a different tratment. It is not above me to swap out a roof for a different version of the car. I'm leaning towards one like this one
even though I like this one better.
Maybe it's the color, as I am partial to black. It looks so elegant, and turning it into a New Yorker would be a stretch, as it would take a lot of time to change the Grille, Tail Panel, and side trim. I saw a one-to-one just like this one at Carlisle, and wish I had the money to buy it. I have a roof section that will work, and my "unbuilt" 300 has "roof rash" like the one you have, so the build may happen.
I did a roof swap on this one...
so it's not too hard of a job. Just a matter of working out the details.
Even though dog dish caps were not an option on the '65 300 series Chrysler, I believe that The Modelhaus has the dog dishes you are looking for. If memory serves me correctly, the ones for the '62 Chrysler would be the same. The ones I used on the '65 Polara were used extensively on Police and Taxi versions in the real world, and yes, they also came from the Modelhaus.
No matter how you cut it, I know yours will be a knockout.
