Nobody has in stock or in production. I find it hard to believe with all you first gen guys running around that no one has any ED3 or 79 CVCC pistons. I think ED1, 2 and 4 will also work but they have to be oversized at .5 mm or .020.
I have parts numbers for Clevite or Mauhle 224-2052 then oversize amount.
or Federal Mogul 12176P then oversize 50mm or 75mm ect
Anyone heard of using other 74mm pistons from other Hondas. I know the Accords or even 2nd gen civic 74mm pistons EM EW D15 motors ect.
