Brand New TRW Dual Brake and Clutch Master Cylinder with 7/8" Bore. Fits all MGA's, All MG Midgets from 1962-1966 and Austin Healey Sprites including Bugeye's from 1958-1966. For Midgets and Sprites with disc brakes we suggest the version with the 3/4" bore. But these will work fine with Sprites and Midgets with disc brakes.
