Hi Ronin,
Cub61 gave you some great info there. My cc100 didn't have the 3 point hitch or sleeve on it when I got it either. I purchased another cc100 for about $300 that had fenders and the three point hitch that I needed. The sleeve was on ebay for 5 bucks.
So I fixed up that tractor and still got $300 for it. I guess what I getting at is there's so many way's to get what you need.
Does your 100 have lights, fenders etc.. I loved to see some pictures I'm a big cc100 fan.
Some of my posts have pictures of the three point set up if you'd like to see how it looks on a 100.
