@MrMoparCHP -- the dates matter.
I repeat my suggestion to look at the April 2008 Collectible Automobile magazine article that focused on the fuselage (1971-73) senior Dodges. I don't have access to my copy right now, as I am halfway across the country from it, but I have a recollection of the author's mentioning the changes that were made to the Dodge. Whether there was a mention of both the front end in 1969 or only of the wider rear track and other restyles in 1970, I do not remember. But if the front end dress-up chrome was mentioned, there should be a useful mention of dates.
Regardless, I looked up in my lunch break the tags I have for the 1969 Polara 500 'verts of which I am aware that post-date the April 25, 1969 letter you scanned above. Here is what I found:
DM27H9D312076 by
@CHASCASH -- SBD 6/26/1969, coded A47, front chrome surround
DM27G9D291517 (was listed for sale and mentioned) -- SBD 5/29/1969, coded A47, front chrome surround
DM27L9D280367 by
@69monaco -- SBD 5/14/1969, NOT coded A47, front chrome surround
Note that DM27G9D231216 must have been built in Feb. or March 1969, and it has the chrome surround.
@rcsfca owns that car and has the build sheet, so you may want to check with him.
