Frame "kit" for that swap does not exist. You can get a frame "kit" for an AD truck but it's going to consist of a direct fit frame with modern suspension, and it's probably going to be a lot more than your thinking of spending.
The S10 swap onto an AD pickup is a swap that has proven to work decent, but it's going to be more involved than your thinking. It will involve at the very least, changing the body mount locations, coming up with bumper brackets, radiator supports and fender supports. it's not that hard for an experienced person, but if you require a kit to get it done, it may not be for you.
