Clutch (using a MGB Pressure plate)

To use an MGB Pressure plate a 9 mm spacer is required under the clutch release fork bracket. Also the flywheel will require re-surfacing and fitting with three instead of two locating dowels. The Bristol Clutch is 8" and the replacements are 8.5"

The MGB centre plate is no use because the splines are different. The Bristol splines are 10x1 and there is a choice of three clutches.
