Did they ever produce a slant 6 4 speed with a console in 1966?

Will the fender tag show the transmission type, or do I need to find a build sheet? I will try to get some pictures tomorrow. I thought it seemed weird that someone would go tho the trouble of swapping in a 4 speed.
The fender tag will show the transmission. It's under the upper case "C" in the middle row. Normally a Dart should have a
1 for 3 speed, a 3 for 4 speed, and a 5 for Torqueflite.
