You could also mount the bell crank from the frame and have the arms going to the rearend. IE: building a brace from side to side that supports the bell crank. Be it round tube, square tube, i-beam, etc... then you don't need to worry about the diffcover.
Take mindliss metals picture. Just imagine the crossmember that holds the bellcrank continuing on till it hit either side of the frame. then instead of the arms mounting to the frame sides they mount off the rearend. same concept just backwards. Plus you could make the center section adjustable in height and dial in your roll center. but thats taking it a little further than it needs to be.
