As of the summer of 2020 steering locks for these old diesels are no longer being manufactured! Your only option if your key is sticking ( and you already tried replacing the tumbler and key) is to try to find a good used unit or a new old stock unit in some warehouse. The lock and release mechanisms inside wear out over time and when that happens a new tumbler assembly will NOT fix the problem. If the wear internally is severe the lock may not be repairable. We only sell these locks inspected, lubricated with a new tumbler installed, and tested. Ignition switch is sold separately. There are so many problems with trying to make these work with aftermarket-made tumblers that we have to test, modify and lubricate (that is right no lubrication in these cheap tumblers) them before installing in a lubricated and tested new steering lock. We feel badly about those customers who have tried to go this on their own only to have the new steering lock assembly lock up on them - and that is a BIG problem!
