Well here is an update, I got the engine in, running and passing smog.
So after that it was time to get the truck into the garage and time to work on it. A couple of my buddies came over and helped me get the bed off. After we had the bed off we saw just how nasty and dirty the frame was. I took a wire wheel and some other wierd sponge looking stripping wheel to the entire rear half of the frame. I then proceeded to mock up and mount the new front spring hangers for the chevy's. I cut off the old shackle mount's and was able to reuse them, so I got those put into place. I got all the old spring's and axle out of the way at this point. I then drug my wider IFS axle under the truck got it mounted under the chevy's and had a couple of fat friend's sit on the rear of the frame to simulate the bed and full tank of gas. I liked the look of the shackle angle so I welded it all the way on. I then used a chain hoist (a come-along on steriods) to suck the spring down flat to set up my bump stops and shock mount's. I made the bump stop's hit at flat spring so that it wont go negitive arch. When the spring is flat and on the bump I have about an inch and a half of shock left to compensate for a little give in the rubber bump. Hopefully I will get started on the front this week. Here is a pic of the begining, and a link to all of the pic's. Not all are there yet so be patiant.
