Your front axle degree is absolutely off as indicated. I would suggest taking a die grinder and removing those perches CAREFULLY.
I have a set of 2" wide perches that might set over the older perch locations and allow you to weld in a newer location. These would be better for you and allow more area for your spring to rest on.
I also have an OEM set of shackles if you need them.
Is that a Michael Knight SPOA lift? It looks like the shackles he makes and sells in his SPOA Lifts. I know those kits are lacking detailed instructions which make it tuff on a new guy.
I will get you the OEM drive-shaft angles this weekend and then you can buy a cheap degree finder from Lowes and set them easily and correctly.
Hang in there your gonna be fine.... By the way that is a nice looking lil Sammy!
