Center console ?? on 66 Dart GT 273 2bbl.
I have both a 66 console and shifter and a 65 console and shifter....The 65 shifter I think could easily be made to work under the 66 console, I was thinkin about that myself. The difference in the stick is round to flat but the black slider that goes in the console is replaceable. You'll have to adapt the linkage with a well placed weld or two but I think that could work, as far as using a 65 console with a link shifter, I don't see that working.
It was also mentioned that the 65 was a one year only..possibly in the Dart, but that same setup was used in the B-body in 64.
