I need Jahns Pistons 11.5 to 1 compression ratio, 3.9125 in. diameter, .9121 pin diameter. The ones I have show #907 or Jahns inside the piston. I am trying to come up with a matched set. So I will need either six Jahns marked or five #907 marked pistons. Three of the #907's were broken. Thanks G.S.
