yep, we been searching that and everything else, been to meets,shows and there isn't much 39 ply. stuff out there.
they would of been in good shape but the guy had them in a 5gal bucket that a bad roof filled up with water for ever.
HEY 39: You might try PLY-DO and Andy Bernbaum. They deal in Chrysler parts and maybe can tell you of a source. I am sorry I do not know their web sites you will just have to play around on internet. GOOD LUCK... DAVE
