I have a set of dana 44's for sale, that would work with a CJ, if you outboard the front springs like I did. Take a look at my sale thread. The front has flat top knuckles which could be machined to accept a hi steer arm. all new brake parts included too except for the rear drums. Gears and drums, would be good to go.
And as an aside, if you really want that YJ dana 30, if you have the dana 300 tcase, you could buy a clocking ring and flip it over to use a driver side front diff. I have seen scotts Dana 30, it looks great, and with the gears and parts included, that is an awesome price.
