Yeah it looks like they may be out of stock... you might try calling Phil to see when they are expected. I was able to call my local parts house and give them the Bosch p/n... took less than a day for them to get it from their supplier. If Phil can't help you there should be other on line suppliers... these show up on ebay regularly as well.
