I just unboxed my Damper Dudes rebuilt 1955 T-bird crankshaft damper. I am very pleased with the damper and overall experience of dealing with Ronald Slater of Damper Dudes. I had read reviews for both Damper Dudes and Damper Doctor, which are just a few miles from each other and within 200 miles of my home. After talking to Ted, however, I went with Damper Dudes. They received my damper on a Monday, and it was shipped back to me 2 days later, arriving Friday morning. 

Ronald said that my damper was in pretty good shape; most of the dampers they receive have been beaten with hammers. Not wanting to hammer/pry mine off, I used the correct puller. I have no doubt that it made the job of removing it easier, while preventing any damage o the damper in the process.

Thanks, Ted, for recommending Damper Dudes.

Mike T, my groove was slight, but instead of polishing it out, they used a new collar/sleeve, which seems to be the standard repair. 

I paid about $18 to ship via USPS, using my box, to Damper Dudes. The cost to rebuild, including tax and return shipping, was $204 and change. They gave me the option of UPS/USPS, with USPS being about $5 cheaper. Living within 200 miles of Damper Dudes, my shipping costs might be less than yours.
