My car used to be painted just like yours.
I was looking for the silver touch up paint as well at one time..........
Chrysler painted the cars, but I think the stripes were painted by Prefix.
That's why the dealers can't come up with the paint code. (this is what I was told by several people)
The silver stripe color isn't a match to any of the Dodge silvers in that year, it's Prefix's color.
.............looking at your car, for me, is like seeing a ghost.
Lots of great memories of good times

..............and one really bad one.

Have a body shop try to match it as best they can............
