They are probably spec'ed in metric, but here are the SAE dimentions.

OD 1.170
ID .520
Sh OD .875 (approx because it is a radiused edge)
Thk .035

Thank you 2xLS1. Much appreciated. If you are wondering why,
I am looking for a spring seat/locator to use the Comp 26915
springs on an LT1. The OD of the spring is 1.29" so I can't see
using a 1.17" seat. Seems strange to have the spring hang out
past the seat,

but it must work.
