About 7/8 of the way down the page there is a link to 'Molex Split Pins Bag of 100' for $30. Yep it's spendy, but what ya gonna do? A buddy just ordered 100 about 2 months ago from this site and I installed on his Mortal Kombat; so they must still be available. Here is a picture from the link. The last pallet of split pins???
