Hi Jack
The TR4A damper you are talking about, which had a rubber insert, was
bolted to the gear box tail shaft, to reduce resonant 'hum' on production
cars. These were never used on works competition cars ( BTW the works cars
this side of the pond never used IRS they were all solid axle).
Best wishes
Paul
