84.8 Piston rings don't exist?

[AJPauly]

Little backstory...
Rebuilding 1977 1.8L engine
Machine shop honed out my cylinders so now I have .10 overside pistons with a 84.8mm bore
Broke some oil rings going in(my bad)
Hastings Piston Rings is telling me the 84.8mm size with 1.5 1.5 3.0 thickness rings aren't around anymore
Midwest bayless has a 84.8mm size ring but does not mention thickness which is necessary to the piston that the machine shop picked up for me
Does anyone know where I can find 84.8mm size with 1.5 1.5 3.0 thickness rings , or specifically oil rings ?
I assume the thickness of the ring set has to be exact I can't get anyone other different thickness rings with the same bore?
Any help would be greatly appreciated!

What pistons do you have? Those rings thicknesses seem odd, as most spider pistons are 1.5, 2.0, and 3.0mm (or 4.0) thickness rings. First compression ring, second compression ring, and oil control ring.
