gregp, the AW Direct hooks are a good bet. If your TC24 bucket is like mine, it has a 2" square steel tube welded under the upper lip as reinforcement for the upper lip, I don't see any reason to put additional reinforcement under in place under the hooks. I don't have them welded on, but I just got a new welder so its on my "to do" list.
I will add a bit of a disclaimer on the upper lip bucket strength, I know there are at least 2 different buckets available for the TC24 so if yours is lighter than mine then perhaps it would be a good idea to put in some reinforcement.
EDIT :: Mine is the 54" bucket.
