Ron, I have a synchronizing tool in the Delco box w/ instruction sheet. Prior to picking one up at Hershey last year, I had been looking for 5 years and have found only one other for sale. The fellow in front of me at the swap meet table who didn't quite understand the function, decided it would be a neat addition to his wall hanger collection and I couldn't talk him out of it. The tool is at my shop and I will not be there until 03/28. If I recall there are three different tools and this one is not specific for my car but I believe it will work.The only difference appears to be the attachment to the dist. shaft. I will be happy to post the info sheet, but I might need some assistance as computers ain't my thing. Dennis
