I am replacing the 904 in my 73 dart with a 727. Will it work with the current cross-member or do I need a differant one? Thanks!

The tranny length and rear housings are interchangeable for both transmissions. T

same mount and cross member

only the tail shaft changed in length

727 shorter shaft

904 longer shaft

I even used a 727 short shaft from a truck with a splined drive shaft in my 68 Dart with the 68 904 mount and cross member

Huh ??? the length from the engine to the trans mount is the same between the 2 , but the tail housing are not interchangeable since the 72 is longer than the 904 and uses a different size yoke .

It seems like you haven't stopped ?

Instead of belittling a person maybe it would be more useful of your use on clean air to help educate them ?

I have personally swapped them, on an AMC, they were exactly the same and the spline for both was a 23. Tim

Think the original poster wants to know if the 727 needs a different crossmember when the upgrade to 727 from 904 is made. Answer is both trans's use the same crossmember, okay?

Well then take that as an FYI , they are NOT interchangleable on Chrysler spec transmissions.
