Abs problems
Are you sure that the ABS block is leaking? Could it just be the lines going into and out of it? That block is billet and typically a bomb-proof part.
This is bull ****. You fix a contaminated system with a $59.99 brake system flush. (Or do it yourself for $15.) It's a scare tactic and anyone who does deserves to be kicked in the *****.
BTW - It's not legal for shops to do an ABS delete for on an on-highway car.
Bottom line - treat this like heart surgery. Go to another shop and get a second opinion. You might also try looking for a shop that specializes in F Bodies. They are out there. If you post to the regional forums here, the folks there might be able to help you find one local to you. (If you do need your lines replaced, this is probably not a job for a name-brand shop. They will charge you catalog rates for the work, which will drive up the price to crazy levels. ... and tell you BS like your system is "contaminated.")
So, here is some information on what happens when Brake Fluid gets contaminated with an oil-based fluid: http://www.agcoauto.com/content/news/p2_articleid/251
You might want to have some of your fluid sent to a lab to see if it really is contaminated if we can't verify your rubber is dissolving. If you do have a cross-fluid contamination, it looks like anything with rubber would need to be replaced or rebuilt. (There are opinions out there that you should be able to flush the metal lines.)
