No problem Len. Glad my question helps for more than just me. And thank you very much for helping me with the pic thing.
OK I filled the struts up with roughly 330 cc an it's not exactly 1/4" from the top because it fills part of the damper tube as well as the strut tube. But it feels fine just want to get this right the first time. I'll try and get some pics on here to help see the big picture.
