    My 8.8 Is pretty much ready to drop in, I just need to buy mounts. I am looking for some tips or a write-up on how most people get the mounts in the right place. I would measure off the old dana 35, but They are different specs so there is not too much to measure from.

    Any tips are appreciated...Thanks guys.

    Why can't you measure off the D35? Determine your center point on both axles (remember the diff is offset on the 8.8) and go from there.

    X2

    Measure twice or several times then weld. Can't go wrong.

    Just because the widths of the axles are different doesn't mean you can't measure off of them. Like Dave said, just find the center of each axle and then measure OUT to the mounts from the center.

    Ok.....But If I am measuring from the center of the axle, I would want a flat part so I can have a straight guideline. However, the only way I can think of is the face of the diff where the cover goes. Am I just supposed to eyeball it everytime I make a measure from the "center"?

    Make yourself a jig to locate each set of parts. Lower control arm mounts, upper control arm mounts, etc. Something like a sleeve that goes in each mount that you can hold in place with just a bolt thru where the control arms mount, and then weld some stuff to them that you have laying around--flat stock, rebar, doesn't matter what, just so you have a jig or template as to the actual distance these parts are apart.

    You'll notice that the mounts are the same distace from the brake backing plates on each side. So now that you know the length between the lower control arm mounts for example, take the parts and your jig to the new axle and measure equal distance on both sides from the backing plates.

    I think you are way over thinking this. Determine the center line of the 35 and measure to the brackets. Find your center line on the 8.8 and measure your brackets out from there. Take everything from the center line and you will be fine.
