CV Flange 16-2303-7

[DirtRider33]

I recently purchased a project build that was never finished. I am working on the rear drivetrain and have a question. 
 

my rear diff has a flange on each side with part number 16-2303-7 on them and the flanges on the hub measure to be the same. My question is what kind of axles do I order? What make and model vehicle would these be a match to for axles. 
 

Thank you for any help

That is a VW Transaxle flange spline for a 091 VW transaxle to a 911 Porsche cv joint, the CV joint in called a 930 CV, due to part of the part number is 930
