Re: piston rings
Hi Richard, yes replacements are available, NOS at autojumbles and auction sites are often in the +0.010 increment intermediate sizes as the majority of pistons appear to be in the +0.020 increments. One of the piston ring suppliers like Cox and Turner should be able to help if you give them the details of the piston.

Re: piston rings
Is +30 from your measurement of the cylinder bore or the stamping on the piston?
