Wm L,
G506's are great trucks on the farm, you should fix up yours! They were surplused by the thousands immediately after the war and farmers, loggers and miners loved them for their 4x4 utility. A little over 150,000 were produced between 1940-45 with nearly a third of them going to Russia under the lend-lease act. Thousands of others were sent to well over a dozen other allied countries. Few of the lend-lease trucks returned to the United States. The G506 was fitted with several body configurations as different needs arose. Many parts interchange with civilian trucks.
