Here is a set up that I found the other day that looks like it would bolt right up to the existing location, has a 1 1/8 bore MC and the pivot for the pedal is built in. It is kind of spendy though at $425.

And this is the set up I'm going to order today to install in my bus as described above by using the pedal pivot on the original MC and fabricating a new pushrod that goes through the old MC and hooks up to the new MC mount a little further back on the frame rail. At $199 it's a significant savings for me.
