this is the original of my car,from what im guessing...the motor works great(because it kept running)the ball im told is not bad,the switch is good too,and the resevor is the factory one with the instructions on bleeding down the system stamped into(my reman didnt have that)all in all the powermaster looks newer,but the pedal was hard and the pump kept running,im told the seals are bad?dont know........................i think $100 is a deal for the factory look,just freshen the seals(so im told)....the core was $50 and no way would i let it go for that i was going to ebay it,but thought i give you good people first dibs...i have a paypal account...ill say $20 shipping...so thats for the first$120 total...
