I have put a front disk brake on my Tbird.  I was going to have the original power booster rebuilt and plumb that into the new brakes.  What I was wondering, since the car is going to be a gift to my daughter, I thought maybe a more modern power master cylinder that mounts to the firewall might be a better/safer play.  I know that will require moving the battery to the trunk.  Any thoughts or even recommendations on vendors who sell a good power master cylinder kit?

Thanks!
