The spark plug spanner I have doesn't seem to fit my 1974 P6 engine as there's not enough clearance between the cylinder head and the plug. Anyone know where I can buy a spanner which does fit? Thanks. Russ

I'm pretty sure a Repco / Powerbuilt socket did the trick on my Rover, but you might be able to just lathe one down by a millimeter or two if need be.
