Bolt, central hub solid drive, Bentley 3 1/2L, 20/25

Note that this bolt has a tapered shank. The 8 mounting holes in the clutch plate GD210 should be taper reamed with a 1 in 48 taper pin reamer in position on the hub to suit the bolt. Once fitted the end of the thread on the bolt should be peened or rivetted over the nut to secure it.
