Yes, but if you get the later O ring box there will be the conversion of the hose. Get the earlier box to simplify. As far as swapping the complete x-member. You'll probably have to take the whole thing apart anyways to replace ball joints and such. I think it just adds work with supporting the engine. You can still use the 69 upper and lower control arms. There will be a small issue with the brake hose/s especially on the right side. I ended up have one made.
