Hi, Spencer, long time no...
Those wire wrist pin clips are indeed a PITA to install. I've never been able to stumble upon a painless method to install them. It invariable becomes a purgatory of mini screwdrivers, awls and whatever. And worrying about the clip flying off to the darkest corner of the shop or into the engine innards. And then worrying and double/triple checking to make sure that clip is seated in the groove. At least other makers use clips that have "ears" bent into the clip so that they can be grabbed with needle-nose pliers.
But, otherwise, it's looking good.
