For instance, I feel confident I could drill and tap the cam, and even machine a spacer to the proper O.D. if I borrowed a lathe, however, getting it bolted squarely on the cam?? nah, wouldn't be so sure. Now, if the OD of the spacer was much larger and I could drill 8mm or possible even 10mm holes so I had some room for error, maybe. But if you look at your spacer in the pic, the bolt spacing is very close to the O.D. leaving very little room for mikey-tolerance
Thank god, I keep records! Here is an archive photo of the driver's side camshaft end. I agree very little room.
