Thank you for your response, unfortunately that was one of the better pistons that I took out. the skirt on one broke off and the guts on most of the rest are pretty well deformed. I'm afraid that if the pistons aren't properly balanced it could cause a problem at high rpm. I have thought about resizing the cylinders but think it would be best to have a machine shop do that so I was hoping to get lucky finding the original pistons.

Hello, I am in the process of rebuilding a Mack model EQSW with a flat head 6 cylinder Magnadyne engine. When I bought it they said it was a 52 but I'm not convinced of that, I believe it is a 49. It had a seized engine so I had to beat the pistons out and cannot find replacements for them. This is my first post and I'm far from a professional mechanic but any help would be appreciated.
