Managed to get all the leaf brackets cut and air hammered off last night. What a pain when you can't torch them off. The fuel tank was in the way on the left front hanger. I have 6 rivets left that I cant get out but I'm borrowing a buddies nicer air hammer in hopes that will push them through.
Next step is to clean up the frame rails, drill the new holes for the 2wd front hanger then paint the rails. That should get me ready to install the new rear hangers and hang the axle.
