Well the 'stock status' at tower says late December so they can't be too far away.

There is a link on that page where you can have them notify you when they are in stock. I did this with an OS FS-70 II carb housing that I needed and as soon as they were in stock I received an email and was able to purchase. The stock status for the carb housing said early December and they came in early December, so I would think their estimates are pretty good.

Also I couldn't find a webpage for B&D and have no idea who else stocks them.

I do know that a few of the guys in the 'Extreme Speed' forum have used these retracts so somebody in there may have an alternate source.
