Thanks for all the help guys. Swap is complete. I went with the vacuum set-up. Changing out the brake was the biggest pain. Trying to get the top bolt out and back in was a bear.
I have tapping as well. Getting worse. Did anyone have knock issue associated with this tap? Tapping is getting worse and car is knocking at all speeds but not at idle. Car runs fine...
Thanks for the info. If anybody reading this knows where I can find vaccuum set up or hydroboost set-up let me know. In the mean time I'll be searching the for sale section.
Im a new owner of an 87' GN and need to know where I can get some parts for my car. The mechanic has determined that I need a BRAKE PUMP MOTOR and a BRAKE HOSE that goes from the brake pump motor to the pressure switch. It appears that I have the original power master setup. Thanks for any info.
