Hello, I am new here. I have a 1990 90 quattro 20V. I just installed new rear rotors and pads. I have to bleed the brakes and master cylinder and proportioning valve. I need a spare master cylinder fill cap to make a power bleeder( I dont have anyone that can help me, so I have to do it myself). I have some spare parts from a model 80 about the same year. I would be willing to swap a part of near equal value if I have it, for the cap. I would also be open to price negotiations for the cap. Can anyone help me?

 

power steering cap sould also fit the brake fluid reservor ... and the ones from the other car should fit too ... and if you still can't find one i can get you one
