Did you ever get the cam install tool?
If you can't find an install tool, one option if you know a machinist (or someone who has a lathe) - I have a lathe but I would not insult a machinist by implying that I am one - is to take a cam brearing to him/her and have them machine an install tool out of plastic. I did that for one of my 6 cyl engines, can't remember if it was for the Falcon or the Triumph. Basically a piece of plastic bar stock, bar OD just under the bearing OD with a step in it for the bearing to slide onto. Also, if you know a woodworker with a wood lathe, they could turn you one out of a hardwood - instead of using plastic.
If your desperate I can look to see what engine I made the tool for.
