search for Matcheless piston sizes

Good evening, after several information on a 1943 Matcheless motorcycle g3l , the disassembly and research phase for the various parts is now starting. I wanted to ask you about the cylinder and piston part. The piston has the size written above and makes 68.98 and of Mahle brand is now worn out is 68.80 and is broken. Where can I find a new piston with the upper size, because I have to bore the cylinder and I don't know what size to buy. Then I find some dealer who supplies me with all the frame and engine screws. I'm waiting for news. Thanks

Thanks, I'm looking for a complete piston with rings. The size of 69.5 should go because I have to rectify the cylinder.
