Porsche brembo caliper brake swap for 473$

Re a later booster, I used one from a 1990's Intrepid on 1974 Dart firewall brackets-lever in my 1965 Dart. I only had to rat-tail file the bracket holes a bit to match the booster's bolt pattern. I used 2 nuts on each stud to adjust the distance from the firewall. The rod fit the lever pin, perhaps I needed a washer to take up play (forget). I didn't use the Intrepid MC since the reservoir was sloped (like yours), but a late 1990's Breeze ABS booster fit and still has inv flare ports (later ones changed to bubble ports). ABS because only 2 ports. Booster barely clears the valve cover of my 273 but I have cast-alum Weind covers which might be taller than OE stamped steel. You can make it out in my avatar.
