They've been very cooperative. Just contact and tell them you're part of the same "Isuzu group with a Vehicross" and want to get the ABS rebuilt for the same price of around $69.99.
I know they did it for somebody else in the past. He told me they don't care if it says Trooper, they definitely can do the VX unit.
Here's their website:
