[Mk2] [NA] Brake disc thickness help?

[mister two]

Tried searching but no luck

Ordered refurbed calipers online as per recommendation on here

They said there's 2 disc thicknesses- 22mm and 16.5mm

Can't measure them today as I'm not home and wanted them sent today. Its a 1997, P reg, uk car, n/a

Any ideas? I thought they were all the same

Thanks

rears will be 22mm, only the rev1's were the narrower thickness
