The rubber on a 1961 3500GT harmonic damper does not look that good. Do not want to see this thing come flying apart. I see there is a company that rebuilds dampers: https://damperdoctor.com/ Does anyone have experience using this company? Perhaps suggest another company. Are new ones available?

Some 6-7 years ago I had to have one rebuilt and this place you note and Dale Manufacturing in Salem, OR were the two recommended. Dale is now retired. Others have had good work performed by Damper doctor though.
