Pard by the time you get a used lower ready to put on, unless you do everything yourself, the SEI is the way to go. Yours should have the 2 piece drive shaft and you use your shift shaft. Hint screw shift shaft all in then back it out 6 rounds or it won`t shift right.
“The world will not be destroyed by those who do evil, but by those who watch them without doing anything” Remember what He has done and remember that He is not done yet! GOD IS GOOD
