Fred,
I have to admit that your message got my curiosity piqued. I did some
research and the only place I can find these mentioned is in a TRF
catalog. I have never actually seen them installed in any of the many
Spitfires and GT6's I have fooled with and are certainly not on any of
my cars.
I suspect that their function is to prevent metal against metal
vibration and the resulting noise. If your mufflers are as loud as mine
are, you probably wouldn't notice it anyway.
Regards,
Joe
