THANKS TO EVERYONE FOR THE HELP, IM GOING TO ORDER THE PULLER AND THE INSTALL TOOL FROM CASCO, THEN I'LL FIGURE OUT WHAT TO DO WITH THE DAMPER PULLEY.  THANKS AGAIN.

The harmonic damper bolt head is 13/16” and the threads are a normal right hand thread.  Nothing unusual about removing the bolt except it’s typically on tight.  Removing the Thunderbird damper does require a special puller to avoid damaging the damper.  A homemade tool for removing the damper can be made to work.  Here’s are some links showing some damper pulling options.

I agree with Ted.  Sounds to me like your damper needs work.  There is practically no slop in my front mount holes.

I haven't figured out how to post a photo.  How do I do it.  I have cameras and smart phone.

I cant get a .003 feeler gage between the damper and the mount.  So i'll have to pull it.  Thanks

While a picture showing a side shot of your damper would be helpful, there’s a strong probability that the elastometer mounted ring on your damper has slipped backwards.  I suspect you should see at the area in front of that ring where the damper hub is unpainted and/or cleaner than the rest of the damper denoting where that damper ring originally resided before it slipped backwards.
 
My choice for damper rebuilding is Damper Dudes.  Hate to talk bad about any vendor but I used Damper Doctor for years but have recently had repeated issues with their rebuilt dampers which forced a switch to another damper rebuilder.

I'm not Phil, but I doubt that there is that much travel in the mount holes.  I had the same problem with a Bird 312.  Unfortunately, to fix it it has to come off and get repaired.  If it's not hitting now, maybe you get away with it that way for a while.

PHIL, COULD IT BE THAT THE 4 BOLTS HOLDING THE ENGINE IN THE MOUNT HAVE ALLOWED THE ENGINE TO SLIP DOWN SO THAT THE DAMPER HAS COME TO REST ON THE "BUMP" IN THE MOUNT BRACKET.  IM SURE THE BOLT HOLES IN THE MOUNT HAVE SOME SLOP IN THE FIT.  CAN I LOOSEN THE BOLTS AND RAISE SLIGHTLY THE ENGINE?  THE DAMPER DOES NOT LOOK LIKE IT IS COMPROMISED OR SEPERATED.

I have used Damper Doctor quite a few times in the past with good results.  Here's a link to his website. https://www.damperdoctor.com/
