3.8

i have an 85 bronco 2 with its original 2.8 5 speed. i also have a 2000 ford mustang with a 3.8 automatic . i would like to take the 3.8 out of the mustang and swap it with my 2.8 . I know there is a tech article on this but it jumps around so much it do not really tell me what i want to know...
