Custom high angle cv drive shafts?

I'm not sure exactly if this is the proper forum, but I am trying to find a company that will manufacture me a set of custom shafts or flanges for my trailblazer. I have a shudder/ shimmy / vibration when the front driveline is engaged up to 30mph on snow covered/slick pavement after my 3" lift kit was installed. The only thing that has changed is my cv shaft angles, which I am going to assume are the culprit.
I would like them to use a Porsche 930 cv joint as they can operate at extreme angles with no problems.
Flange on left is a stock 930 inner flange, right was one modified for a Grand Prix gtp

This is the 930 joint, version 1. Version 2 I haven't been able to source which keeps the bearings separated instead of 2 coming together in pairs like this does.

These are my shafts specs..

Anyone have experience in tackling a chore like this?

How about your driveshaft pinion angle?

How about your driveshaft pinion angle?
The issue is with my front IFS CV drive shafts, not my rear driveshaft. I have no vibrations in 2HI, the truck is rear wheel drive in 2HI.
In 4HI the shudder/ vibrations are felt through the steering wheel and body.
Here's my cv angle, you can see the shaft doesn't rotate true and might be binding up.

Way too much angle, you are correct. I have never seen a high angle cv axle. You need to google what you are looking for.

I have, lol....
I get rcvperformance and the driveshaft shop as the two top hitters. RCV want $2500/set and DSS wants $1500-2k set.
Not exactly what I want to pay, thus reason for trying to network and see if others have had some made elsewhere. I don't need a bullet proof set like these shops want to make, something middle of the road and $800-1,000 range is more what I figure it should be running me.
But I'm going to assume due to such little feedback, I need to post in other forums.
