Hydroboost braking systems
I have installed many of these systems exclusively on Mopars. I am also a dealer for Hydratech brakes. While one may be able to scrounge the JY for parts, when it comes to liability, I don't know why anyone would take the chance if you are installing these professionally.
This is a great system, and I've had one on my Dart since 2006. Call me at my shop 631,423,1517 or PM me if you want details or want to make a purchase.
