T5 Clutch Master and Slave Cylinder bore
 

Does anyone know if a 7/8 bore clutch master would be okay to use with a 7/8 slave cylinder on the T5, or would I need to use
a 3/4 clutch master with a 7/8 bore slave cylinder?
I would like to use the Tilton master cylinder with the 7/8 CNC slave cylinder, and I think the CNC slave only comes in 7/8.
