power steering box removel on a 67 barracuda

Just replaced the power steering box on my 67 Dart with a 273 .Pulled starter, took nut off of drivers si
de motor mount, jacked up engine, pulled steering column, and let gravity help me take it out from underneath. Didn't have enough umph to lift new one from bottom, jacked up engine a little more and was able to lower it in from top, buggered up threads one one hole and had to pull it out to run a tap through it, then box back in.
