I HAVE A CUSTOMER THAT HAD A GECKO DRIVE, INC. 120911 DRIVE FAIL. THE PART NUMBER IS G723 - 400 - 4DS 5.00A. THIS ISSUE IS THAT GECKO DOESN'T MAKE THESE ANY MORE AND I NEED TO REPLACE IT WITH AN EXACT DUPLICATE OF THE MOTOR AS I CAN NOT MODIFY STEPS, CURRENT, ETC. AS THE CUSTOM SYSTEM DOES NOT HAVE ANY DOCUMENTATION. CAN YOU HELP? TROY
