Hy Lori's 66, Hy I didn't think this was appropriate for your weekend updates posting, so I'm puting it here. I noticed that you said you were going to convert the rear axle to disc brakes, and that you were also going to change your master cylinder. You may realize this already , but just in case, the master cylinder for disc brakes is different from one for drum brakes, the disc master has no provision for residual pressure, required for drum brakes. So if your going to change the master make sure you get the appropriate master for the brakes your using, hope that helps.
