8 1/4 rear disks

Good call changed the master when I was doing the brakes, prob a 3/4 master (rock auto) . Just received a 1" master and power booster. Should put it in soon. changed all lines, rebuilt the calipers, new drum cylenders, proportional valve and rubber lines. That is one of the reasons the 225 is still in it to work out all the bugs. All the rubber on the car was OEM including the coolant! Suspension is now poly, I figured there would be problems! Glad I live in the middle of nowhere to work it all out before it goes on the road.
