First step- off with the grips. No problem there, I'd had the grips off before.
Now comes the good part- pushing out the clip pivot pin and I got to use my pin pusher bit for the first time and it was too short to push the pin all the way out (probably a good thing too, who knows where that spring might have gone)
While containing the clip button and spring, I removed the pin fully without incident. 
What follows could not be photographed and yes, I could have used three hands to install the new spring. Between the pistol sliding around as I compressed the spring, to jiggling the clip release button to line up the holes, to pushing the pivot pin in, it was an adventure that went on far too long, but did end successfully with new springs and a fully functional pistol, I hope. Next comes the new Wolff firing pin spring which also has me a bit intimidated. The pictures I've seen of the process leave too much to the imagination for me and all I can see is dark blurs of metal inside the slide. I'm going to have to do this one in daylight. My eyes need the light........
