888-892-0764. Talk to Leslie. I gave her the p/n you have posted but it does not come up with that number. But she did indicate she thinks she knows which one it might be, If not she indicated that they MAY be able to rebuild yours.
Give her a call, good luck
P.S. Your brake system should function properly with ABS offline, you just will not have the anti skid function operational.
