I have a 1951 3600 and Its all stock. I just cleaned up the the leaf springs and joints really good in the rear. Greased everything back up and I can tell the rear end is much more functional. Not so stiff. Tomorrow I am taking off the original tires and having them replaced. In the mean time I will be Cleaning up the leaf springs and joints in the front. Installing new shocks. Once I get everything back together Ill let you no if there is any major improvement. If you haven't done so already Its worth a shot!
