I let my Erie Dearie Style and Silver Buddy style molds go a long time ago and it took me time and money to get them back and I won't let them go again!  they and the weight forward spinner molds show up on Ebay but you'll pay for them!! Put a search on ebay and they'll notify you when they pop up.  Also check out all the bass boards and you might find them also.  I've got a couple of Ament jig molds but being older molds you do a bit of trimming.  

Jigfishn10 nailed it - attach the blade to the first swivel with a split ring, and then either tie with heavy thread the swivel to the shank of the hook or as others have said shrink tubing
