Spent a little while doing measuring and scheming while I was rebuilding a CV axle and filling the diff before reinstallation.
So I came up with more chicken scratches. ... Can you tell I was doing CV things? (grease)
This drawing is to scale- except for the frame portion of the car. Disregard any lines with x's through them. Sorryi its a mess, but this is the easiest way to convey my ideas at the moment.
So this is a drawing of the uprights (obviously). I'm thinking I'm going to have another set cut from 1/4" plate from my waterjet connection, when I get a good design.
The hole with the "+" in it is where I would cut a circle out of the upright, and install a sleeve, with a poly bushing (just an idea to make it a little less harsh and transfer less vibration). That is also just a tentative location of the mounts - not sure as i don't have a diff yet.
The R200 cover, and the 8.8 cover are both 3" thick from the mounting face, to the gasket face. The only difference being that the 8.8 has a larger ring gear, and will likely shift the carrier ~1/2" forward. I am thinking that I could make the upper horizontal portion of the upright longer, which would shift the "mount" further back, and then just accommodate at the bottom for the same amount.
The front face of the uprights are within 1/4" of the front face of the mustache bar, because it curves in in the center. Essentially with this design, the mustache bar would be completely eliminated and removed, thus putting more load on the uprights, and me wanting it thicker.
The bottom drawing is kind of what I have in mind with the "sleeve" idea. For those of you that aren't aware, THIS SITE is awesome for individal bushings.
