What year is the "RT" ?, looks like '73/'74, is it a Canadian Dart?
I believe the other Dart R/T was a '72, so this might be another proto-type car. I was looking for the original thread, but came up blank. How many more is there?
Is is a slant 6 RT?
Where is that crack smokin frog when you need it?
I don't know where the frog went, but maybe this will help.
