I'd agree with the $50 t0 $100
The one I have in my Dart I got for free.
It was on craigslist along with a 318, he was trying to sell both together.
I called/email him a couple times about just buying the tranny. After several weeks of his combo not selling, he said, you want the tranny, come get it, its in my front yard still attached to the engine, I just want it gone! Probably could have gotten the 318 too, but I didn't have room to store and extra engine.Fresh oil, filter, and a front and rear seal and it works great !
