Slab pistons 5100 and 7900 are a lot lighter.  Don't remember how much tho.  I can get wt's on 7900 if needed.  IIRC i wrote the wt on the box.  I used windowed piston in my Solo 665/681 conversion because I went too wide on the ring end side.  The windowed piston pin is in the middle.  The slab pistons are in the box.  I need to send em and have the pins relocated.  I did measure skirt width the slab pistons are a little wider.  Interesting the Solo 665 cylinder is quad port like the 7900 where the 6400 is open.
