Contact Dicor at 800.837.2059. They will direct you to the one person in-house who handles these. I don't remember his name off hand.
Pedestal is P/N IP-15300, $245
Slider is P/N IP-153481, $135
The slider is fine, however the Dicor pedestal is unsuitable as is only has 3 preset positions or detents. The Springfield is variable and clamps to desired height. You can use the Dicor 4-way slide after the table mount of the Springfield is cut down- which one can do with a skill saw.
Ask for Jeff Sbirt.
