Default Crankshaft Damper Not In Harmony

Chasing some unusual noise at startup that goes away within a minute, and eventually narrowed it to a suspected crankshaft damper de-lamination. After searching the archives, saw several helpful mentions about painting white lines on the damper and crankshaft pulley, then starting the car and let it run a bit, shut it down and check if the lines still align. Good news, I identified the noise, bad news I need to replace the damper. Or rather I need to remove the damper and send it out for refurbishment. Ugh.

There are several aftermarket dampers for sale, but they all seem to be MTC or Vollig with neither manufacturers having great reputations for quality. My assumption is that I would be better off sending my original damper to Damper Dudes or Dale Mtg (if they are still in business) than buying a aftermarket replacement. Do you gurus agree with that assumption?

It looks like it will require removing the air bleed piping, the radiator top cover, the fan and fan shroud, and the various belts to gain proper access to remove the pulley and damper -- is that correct?

I saw the Wizard of Oz's great tip of bump starting the engine to loosen the damper bolt, which is not only clever, but should guarantee the engine isn't turned the wrong direction. Any other tips I should know before I get stuck in?

Thanks

I would take the rad out too Mac. It is not a great deal more work and makes anything on the front of the engine far easier. You can also see if there are any other small things that can be done easily as well.
