Yukon posi unit and gears

[need boost]

Anyone have any experiance with them? Seems there are a lot of guys with the v8 buicks running them and have no problems at all. From what I read it is a clone of eatons, and American made . The gear sets seem to do excellent as well. Just wondering if anyone here is running one. Here is an example

You can't use that package because it's for 30 spline axles but you could buy new 30 spline axles if you wanted to use it.

Stock axles for the GN are 28 spline.

I am upgrading to 30 spline axles after twisting a set of moser 28s in half. Just wanted to see if anyone has run one on here. Thanks Daniel Ray
