Installed new master cylinder yesterday..that did the trick..(hoses were ok)....thanks to Big G for his input....
I also installed a new seal kit/bushings,etc in the steering gear cylinder...odd was the threaded portion of the rod was bent slightly...did not want to bend it back for just 1/8", sooooo.....don't say "bubba",as I just want to "service evaluate" it...

My brakes need some attention now. Pedal is very hard, very little brakes. The master cylinder fluid level seems to be right where it should be. Could it still be the problem? How do I troubleshoot it?

Test of booster:Vacuum Leak Test....
1.Operate the engine at idle without touching the brake pedal for at least one minute
2.Turn off engine and wait for one minute
3.Test for vacuum assist by depressing brake pedal and releasing it several times..if vacuum is present in the system,light application will produce less and less pedal travel.

Also, I was told to remove the hose from the booster to the intake/carb, with the car running. Don't know if all Vettes have this. Mines a '75. If I have suction on the hose, then the booster is bad. Well, I had good suction and white smoke coming from each tailpipe. So I guess it's time for a new booster. Don't think this one has ever been changed out.
