Jerry,Im no trying to shy you away from, the job,but if you plan on towing a lot of weight,or turning up the power,then this is the time to upgrade the 3rd gr clutch,and the seals. Call Bill K tollfree 1-866-504-4002 and he'll help you determine what you need,and help you with install advice. he walked me thru my first one,easily. I did my own installs,I did some internal upgrades as well,if your going to have the unit out,it is the time to upgrade it.
