Samuel,
You've obviously found a third size PDWA used on the TR6. A good seal
supplier ought to be able to help you out as these rings ought to be
standard sizes.
I'm not sure about the .096 width you state. If this is the size of the
old rings you took off then some shrinkage may have occured as the
closest standard size is a 100 series ring, .103" +/- .003". Again, the
local supplier ought to be able to help. Just make sure they are
Ethylene Propylene (EP).
