The first one is probably a 2002-2005 autococker, but without seeing it I couldn't be sure. It could be any number of things.
As for converting the VF tactical, there isn't an off-the-shelf kit that will work.
I'm not positive, but I think it might be possible to use a 2K Minicocker pump kit in conjunction with an extra-long pump arm. Don't quote me on that.
Another option would be to cut the front of the body down to "normal" minicocker spec and again use a 2K minicocker kit.
