Installing older versions of Numpy + Matplotlib (virturalenvwrapper-win)

I'm busy setting up a virtualenv for my ArcGIS 10.3.1 Python (2.7.8 64bit) Development. I've created a new virtualenv using virtualenvwrapper-win and it's installed a clean installation of Python based on the current default version installed by ArcGIS. I trying to install the ArcGIS required versions of the following packages:

  • Numpy (1.7.1)
  • matplotlib (1.3.0)
  • xlrd (0.9.2)
  • xwlt (0.7.5)
  • Pyparsing (1.5.7)

When I try to install Numpy (1.7.1) and matplotlib (1.3.0) via command line using pip install, it fails as it can't find a Python Wheel for the following and only finds a zipped file that it tries to compile and fails. I don't have any experience in how to achieve the following. I tried downloading an executional installation for the following but unfortunately it doesn't give you the option to select an alternative installation directory but the default Python installation under my C Drive. Any help to solve the following will truly be appreciated.
