Looks good. I would position the rear end with the axle yolks 13 inches above the ground (or whatever your tire radius is), then put the frame rails at your desired ride height and see how the mounting ends of the batwing match up with the frame rail. Since the batwing appears to be wider than the frame rails, you may end up having to do some modifying of the rear frame rails where the batwing mounts will be to get the right geometry. I would also make the forward links longer than the existing C4 dog bones - you have plenty of room. Consider having the front pick-up points of the forward links adjustable - i.e., multiple holes for each link much as most four link set-us have.
