The rearend can be tricky...save your old one when you take it off. If not, plan on taking your time and buy an extra length to do it again. Be prepared to bend some and when it starts to go bad, stop for the night ( or day or whatever)....
If you buy a kit, you will still have to do some extras for the double master....unless someone offers a kit for a double. I did not see one for my 46.
