Yes I did the install on my suspension. I have done three other Installs of m-10s in the past. I would suggest calling and asking for Brian it might take a while for them to get back to you by email. As musselman stated the front shaft is the only thing you should have to buy I think around 40$. I have the same type of financial advisor . I used both sets of directions for mine but I would ask what has changed since that time it could save you time.
