Firstly, I want to thank user CA189HJN for selling and shipping me every part I needed to attempt and succeed at this modification. It has been done before, but here are my anecdotes, regardless. If they help anyone here I am happy to elaborate further, just shoot me a message. Above is what I consider to be the finished product of months of effort and research. I am going to post this and edit it as I develop the thread. The previous owner of my car had installed the ‘masterpowerbrakes’ front disc brake upgrade. I was happy to buy the car from him knowing this mod had already been done. A week after buying it from him and I noticed at every stop light my pedal would slowly go to the floor, despite having no external leaks. I contacted MPB and they shipped me a new master cylinder. Problem solved! Only after owning the car for a year after that did I consider power brakes over the current manual configuration, and it took yet another year to complete this power brake phase; one month for the install, 11 months for research and parts! This is my firewall unmodified. ^ This is my firewall modified. ^
