oneofapair should be qualifying in the top 10 on the grid
83.5 mm is a common Ford crossflow , Bda / lotus twincam size . It may be worth a look on a Ford/ Lotus website to compare sizes . Burtons, QED, etc. Altenative may be looking for a ring manufacturer listing ",Deves" and "Hastings" are ring manufacturers, also seem to remember possibly a company in Bradford, can't remember name though (Bradford piston rings?)!

Good Luck
