I havn't found a single one. Nothing. If you can stick to a standard size shaft (1"?), you may be able to find a used one off a V-drive. Otherwise you can have the prop custom built. Menkins is one name that comes to mind. I've researched the blower on a flatty option extensively. There is one guy that is offering a kit (I can't recall his name right now), but it's a little contemporary. You might find a link on Red's headers. The only guy that supposedly still has the intake to mount a GMC blower is Navaro (sp). A 4:71 would be perfect. Good luck finding the 3 pot carb setup. Big $$. The little scoops that you sometimes see are still available.
