Reply:Very nice build... Now this is going into a jeep? Lol my goodness this is going to be a tight squeeze!! The weight on the front end... what type of Axles are you going to be running? I would suggest something on the lines of a Dana w/ 4.10 gears. Your putting a 5.5 lift on the front and rear correct? Is it going to be coil over springs? Do you know the Gross weight on that engine after its all said and done with your add-ons? You will have to cut your hood and put a very large Cowl on there. with real air intakes. I am sure you have measured your clearance?Last edited by AndrewDavenport89; 06-11-2015 at 02:25 PM.

Reply:Yea that springs right there will hold some weight lol(I am referring to the spring on the right). I forget, but the shock rides on the inside of the spring and it all sits on top of the front leaf springs correct? Have not looked at that model jeep in a long time. How much longer until you start working on the truck itself? You just about have the diesel wrapped up. Just a few more bells and whistles.

Reply:Got the flywheel back from the machine shop and went to work on the clutch, I sourced a new pilot bearing from the local bearing supply but the minor diameter is 1mm to large so I made a bushing the is pressed into the bearing and has a good slip fit over the input shaft
