hey any one who knows please help i just purchased a 75 440 and trans out of a motor home to put in my 72 challenger. The tranny has that short tail section with the brake and flange hook up for the drive line i need to know if i can swap that tail section with spline yoke for a drive line from the original motor wich was a 340

 

i know you can swap it out , not sure if the SB tail will fit,

 

sb tail is diffrent as far as I know, hope your rebuilding that motor becuse its going to have next to no go for that year
