What are you looking to spend on them I have three here right now.

Trucks were long tail and have a cast iron case. A and F body some were all aluminum with a 30 spline output short shaft.
I've had a few aluminum truck units such as the original one in my 79 van and have another one now.
Cast versa iron case is an early/late thing

Are you looking for a short tailhousing to fit an A or F body? small output shaft or large?
The A/F body unit has a short A body tail housing with one shifter pad.
The truck/van unit has a long B/E housing with 2 shifter pads.

Truck/van unit.
Also all the 833OD units use the larger spline tail shaft. 727/833
That would be for a B Body or E Body. They came in trucks or vans.
For A and F bodies there was a small spline O/D made, same spline count as the 904 and some early A body 833's.
Lower first gear and a .73 O/D in 4th gear. But you have to flip the first lever from up to down. You might have to fab a 3-4 shift rod.

drove it first in 1987
For me I am done with trying to mash gears and drag my 340 up to 7000rpm. I just want to get on the highway and cruise my Dart at 70-75mph and still have some low end. I have a mild 340 with 484/284 M cam, aluminum heads, RPM manifold, fuel injected factory 4spd car. swapped the 4.10 to a 3.23 and at 2800rpm I'm doing 63 mph, I run 275/50/15's. Yes a 3.55 gear would be great with this set up and cruising the hood but I want to actually put some miles on it. Now the modern 5spds can fix this but I am not will to cut out a 4spd tunnel to replace it with an auto tunnel so I can put a hole in the floor for the modern shifter. GearVendors option; I am not interested in a tail shaft swap along with shimming the trans angle down to clear floorboards and beat room in the tunnel for the unit. So for me and my wishes for the car I have owned for 23 years I am willing to try a OD 833 and see how it goes down the road. IMO, the biggest mistake people make when playing with their car is not being realistic to what they plan to do with it.
I cleaned up this thread. If you don't have a transmission for the OP do not bother responding to this thread. He can do his homework and buy what he wants.
Sounds like you should have an A body O/D. Or did you swap a B or E body 4 speed into your Dart? I have an extra A Body O/D with a swapped standard main housing and 30 spline output shaft that will replace an A Body 4 speed. It may be all cast iron though. I'd have to check. All you would need is a O/D 3-4 lever and rod. I reached the same conclusions you did years ago. It worked great behind a 273, should work even better with what you have.
