Diamond Pistons for 416 stroker

The part number on these is 51008 and everything you would want to know about them is here [ame]http://www.diamondracing.net/pdf/MoPar-Section.pdf[/ame]. I pulled one piston and the skirt measures 4.065. I don't know if that's considered collapsed. They were in good enough shape that my picky builder was going to re-use them. This is less than half the price of new ones.
