Dodge Dart GT Questions 1968-1969

Hi everyone,

I have a question and it is on the 1968-1969 Dodge Dart GT. I have found two GT's and both are saying they are slant six cars.

My question is can you tell me if they did put a slant six in a GT in these years?

I have not called about these cars yet but I also have a 1969 340 car kind of drop into my lap and I need to find more out about it. The car was torn down for a full restoration.

I'm really interested in the two slant six cars. How rare would the slant six cars be?

Thanks everyone.
