I just took my factory handle apart and after I cleaned it up realized my ignition key fit it and it works. It was so crudded up inside the key never would even go in the key hole. Once I got the tumbler out I was thinking I could have it re-keyed, but turned out I don't have too. I took it off about 25 years ago and replaced it with an after market one so I could lock it. I saw the factory one in a box the other day and decided to take it apart and mess with it. There is a little nipple on the end of the tumbler that activates a the small lock pin when you turn the key. Mine was worn off, so I welded a small glob on the tumbler and ground it down to fit in the lock pin. Works good as new now and turns out after all these years the ignition ket still locks it. I have not been able to find a quality after markert one comparable to the factory one and glad I decided to tear it apart.
