Monte Carlo Z34 brake master cylinder options/ ABS delete?

[carkhz316]

As the title states, I'm looking for any/ all info in regards to the proper master cylinder needed for ABS deletion. I'm only wanting/ needing to do it in order to fit turbocharger piping in the engine bay, and not because of some naive safety circumvention. I am already running a smaller first gen brake booster found on the manual transmission cars if this matters. While searching RockAuto, there seems to be a lot of overlap between the 1st gen W-bodies through 1.5, with and without disc brakes, etc. So, I figured I'd ask the experts since I've seen brake systems discussed here in the past. Thanks!
