Got it running!
Yesterday,I got bro-n-laws 59 running.We actually took a ride up and down my street.I couldn't get it into reverse so had to push it back out of one of my neighbors driveway.Still have plenty small issues but the main one is the brakes.I had the master cylinder rebuild by White post.I bled the brakes with bro-n-law pumping and holding while I bled each wheel cylinder.Didn't bench bleed mc.Even though I have decent stopping there is a lttle fluid coming out of the bled hole in cap when you push on brake pedal.I called white post to see if they could help and they said to be sure the gasket for cap was in place.It was in place but I don't see where gasket has any affect on leakage though vent in cap.He said send it back to them.I really don
t want that delay.Any help appreciated.Thanks, Eddie

You may have over-filled the master cyl. reservoir. It should not be filled to the top....you need at least a half inch (or a bit more) of air space in the reservoir. There is no 'bleed hole' in these units....only an outlet line. And you should never install a master cylinder without bench bleeding. It's an easy, 2 minute process that saves hours of grief.

I believe the '59 master cylinder has a vent in the cap but still sounds like it's overfull.
I've never personally seen the need to bench bleed a single reservoir master cylinder. In any case, not bench bleeding the MC wouldn't cause fluid to come out the vent.
If the brake pedal is solid and the car stops good, I'd check the fill level of the MC.

You may have dropped the plunger in the reverse lock out on the shifter. If it's like later models take the ball off and remove the collar and see if the plunger comes with it. If not pull it out then screw the ball on and see if you can get reverse. If not go underneath and check the linkages.

Mike's advise is spot on, the cast plug has a small vent hole, remove some fluid so that the top of the filler neck has an air space. About 3/4 in works well and allows room for expansion. Never had to bench bleed that single master cylinder either.

My master cylinder definitely has a vent hole.I'll drop the level to about 3/4" below top and watch it,thanks for the help.I lubed the shift linkage the was able to get car in reverse.After that first time it's been going in reverse pretty easy now.
