I looked for the thread and the pictures showing how some people have installed the 2 bolt cast flanges for the inner bearing to no success, if you look though the Max gallery you will find them.
Basically the left side is straight forward just bolting the flanges to the frame rail, the right side is a tad more complex as the c-channel faces the wrong way requiring mounting tabs welded in.
A more intense installation was done by Jerseybigfoot who also converted to newer style splined axles and sprockets.
