Hello I have a 1964 Barracuda with a mild built 1970 318 and a 4 speed thinking about switching it to a automatic I have a built 904 and was wondering how much of a hassle it is

It's easier if you have the correct early 904 but not that much more complicated if it's a later version. Tell us more about about the trans you have.

the physical part of putting the trans in is no big deal. it's all the peripheral stuff that's "gotchas"

you'll need a kickdown assembly for the trans (aftermarket cable is easy)
fluid lines for a cooler-- external if your radiator is not so equipped
shifter, aftermarket floor is easiest
driveshaft will need to be modified. 904 is shorter than a833, the output is dependent on what you have currently and what you're going to. basically flange mount or slip yoke.

The transmission I have is out of a 70s a body probly 70-73 with a stage two rebuild kit shift kit and I have a 70 318 in it now so I don't have to worry about the spacer for the crank am I going to have a issue with the transmission mount is what I'm wondering

This is what I have B&M shifter after market cooler I can make the lines I know the driveshaft will need work is Flange mount kick down I'll use the Locar like we used in my kids truck I guess my biggest concern is the mount for the transmission is that going to need modifications it has dual exhaust that is out of the way and I guess my next question is what headers are people running in that car

mount is the same, no worries there.

headers are limited: TTI, doug's and sanderson are your best options.
