Harmonic Balancer Separated when removed - Repairable?

Follow-up, with a happy ending.

So these Harmonic balancers are actually easy to remove and replace if you use the correct tool for the job. After I chose to use a gear puller to remove the stock unit (ripping the outer ring off of the rubber layer), I swear I heard my grandfather's voice in my head: "you gotta use the right tool for the job".

So I went out of my way to install the replacement harmonic balancer 'properly' (which was so generously donated to me by fellow ABodiesOnly member diymirage). I bought the 3/4" fine-threaded bolt, finding one that was 1/4" longer than spec . The other option was one that was 1/4" too short.

Therein was the problem. I tapped on the balancer just enough to get it started, and then screwed on that massive bolt, with a washer contacting the front of the balancer. Tighten it up, and on it goes! So far, so good.

Then it stopped before the crank pulley lined up with the water pump pulley! It needed another 0.2" to line up. Nope!

It turns out that the bolt had run out of threads in the crankshaft snout, since it was too long of a bolt. Which took me a while to realize. A stack-up of washers between the bolt and the balancer provided the fix; I was able to get the pulleys to line up just fine.

Note to others: buy the 2" long , 3/4"-16 bolt if you can't find a 2.25" long one (not the 2.5" long version!)
