    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.

    There are no leafs on a TJ, it is a coil spring setup, you would never have both as that would make for a very intersting ride with 2 springs constantly fighting each other and the shocks are outside the springs.

    Is that poor little jeep going to be able to hold that 750lb motor?
    I'm curious also. I have a friend that installed a 4bt in an Expedition. Before he found some beefier springs the fenders where rubbing. He was hoping to get by with the stock setup. It did fine after the heavier springs were installed.

    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
