Recently my 08 corvette just had an ABS modulator valve kit (89060303) starting leaking break fluid. My warranty company and parts manager had me in a loaner for 6 weeks trying to find this part. They finally called me today and said they gave up, and can not find this part anywhere!

How can they discontinue a part on an 08?

Where can I buy this part, not one website has it available after I call.

I mean, this car is 6 years old and there's not one part in America? My warranty company said they'd pay for it and the labor but it has to be new.

Any help would be appreciated.
