#1 What is an estimated time for installation?... .
As Briar has said 4-6 hours depending on your skill level and the tolls to do it,8 or more with problems.
It took them 4-6 hours at the shop to do mine with the 5th gear nut update,new slave cylinder,carefull work not to get truck dirty and the test rides. If you decide to let them do the install it is worth the trip. EEP's customer service is second to none and they are a great bunch of people. Heck they even let me tour,oops,get lost in Ohio for them. . LOL.
#2. Where is a good place to get a centering tool for a dual disk clutch locally?. .
When you call EEP and chat with Doug why not ask him where to get what you need. If he doesn't have it he may be able to steer you in the right direction.
You will be plenty satisfied with the unit,I know I am,best money I ever spent... ... ... ... Andy
