Bobcat Laser Grader - Your help needed.

We have been plugging away trying to get the Bobcat Laser Grader system to work on all machines.  We have a customer with the laser installed on his Caterpillar.  It works externally from the machine using the Bobcat control box.  Our goal is to integrate it into any machine so it will just work.  We need your help as this customer needs his machine back.  Does anyone have a set of BLR2 receivers and a dual slope laser that you would be willing to lend us or sell us for cheap?  We need this so that we can continue to explore the issues and come up with a bullet proof system that will work.
