Working on a JD model A and I'm trying to determine what size woodruff key is used on the Delco 1111558 distributor to hold the lugs on the shaft. I have tried a few keys I have around here but can't find exactly what size is used. I know I can buy a rebuilt kit that includes that woodruff key. I am just trying to get it back in working condition as soon as I can, and shipping for that $15.98 kit is an additional $ 25.95 for the bushing, key, nut and 3 washers, which seems outrageous. Anyways, anybody know what size woodruff key is used on this distributor? Thanks in advance for any help you can provide.
