I just called, the rear is in the car but because it's a 4 channel rear - apparently contemporary corvette sent me one with traction control even though I said not to - they need to order a brake line kit for the 3 channel to run back since 3 channel has one line 4 channel has 2. They said it probably wouldn't be worth it to try and get a 3 channel rear from c.c. because this one's already in the car. I dunno, I guess I'll just get the brake lines and no abs and call it a day
