i approve of this seein as its a 7.3 lt
now ya need to check 2 things on it as they are important
1 check oil pan to see if its rotted and leakin oil as its a motor out to fix it
2 check the adapter plate on the trans - t-case and make sure it isnt cracked or broken as it will estroy the back half of the drivtrain esp beein a 5 speed and it is highly common
