Anyone have the exact spec of the torque tube O-ring seal that sits in the clutch bell housing groove. Measures about 98 x 5.5-5.8mm.

Gives sizes, it'll either be a metric or BS (and at 98mm, I'd start with the BS...)

Chemical wise, no idea, but given it's location I'd go for a Viton to give some kind of oil resistance

Well I got a 94.x mm(ID) ring which fits but is bigger than the original. The 98mm above was a centre-centre dimension, latest efforts consider it to be 92mm id. I think it will do the job. I have 4 more if anyone wants one.

The next size was 89.x mm, might be too small so I figured I can cut and glue if necessary.

I think the content is likely to be a lot more than this.
