Photo request. 1966 dart manual transmission stuff

Hey guys, I recently picked up a 66 dart sedan with a slant six and three on the column. I was looking to put the shifter on the floor. Do any of you have a photo of what the shifter and the hump would look like? Finding all kinds of different stuff on the web.
This would be a non console shifter.
Also, I was curious about three speed floor shifters and linkage. Hens teeth?
Just trying to figure out what I'm in for when doing the switch. Parts availability, cost, rarity, etc. Maybe better to just go to a four speed?
Anyhow, thanks in advance for any help.
