Has anyone built or no where to buy all new hangers and shakles. 289,000 miles, 15 Michigan winters, and the backwoods have all taken a toll. I have new steeering, springs, shocks, body, and a solid frame but the hangers and shackles just don't look trustworthy anymore, the rear hangers have holes rotting in them, and the front spring hangers look tweaked, need advice on construction or replacement, I have a hoist, welder, torches and anything I'll need to rebuild the entire truck.
