Tool Trend has them. I couldn't find them in any of my other catalogues. At $49.90 Cdn. they aren't cheap, but if they do the job nicely, I guess they're worth it. Their online catalogue is rather limited, but you can order one for free. Link below.

Pete, any reason why you removed the L-shaped plastic hold-down blades from the handle slots? Did it make repositioning cumbersome?
