1991 Gran Sport has VERY unique Master Cylinder
 

My Regal has a leaking Master Cylinder that costs $1800 new because GM designed it with the ABS module integrated into it as one unit. There about half that price if you can find one used and no one guarantees they will work following the install. Check out the picture and compare to a NORMAL master cylinder I found online picture of another car same year and model. Anyone know any real experience with one of these ? I have let this car sit for 10 years because it was my Dads last car and I want to get it back on the road. It was a nice ride. HELP !
