Photo request. 1966 dart manual transmission stuff

A 4 speed would be the way to go,With the 6 you;d want to use the 63-65 4 speed trans , bell , shifter , and floor hump .It's a bolt in with the right stuff with only a cut out in the floor under where the hump goes .I've done it a few times . The parts are out there and can be had pretty easily . I have this set up in my 65 Valiant station wagon .It had an automatic with a tired 225 when I started with it and now it's a 170 with a 4 speed and lots of fun to drive.
How much do the 4 speed /6 bellhousings run, any available? I know there are some, friend and I looked and searched for one in early '80's, couldn't find one, wasn't sure then if they existed except for a truck-large flywheel. But as of lately, I understand they do exist and many of you forum members have vehicles witht them. When someone mentions 4-speed slant, I get closer to the computer screen.
