I'm just curious about something here. Have you or anybody else for that matter given any thought to the possibility of using or adapting parts from the Dewalt 788? They are so close in design that they just might work. Also, Pegas has designed and produced clamp kits for both the Dewalt and the Excalibur, Jet, Seyco that they might be usable also. I'm not sure which parts you are in need of but by trying the Dewalt, you might be able to get your saw back in operation. Just a suggestion.
