GKN 108 Joint Spline Data

Hi, I had a friend at GKN who was helping me with this but he`s too busy expecting his first child, he sent me a drawing of the joint and did some maths when he recommended the joint in question but I would really like an adult to generate the male and female spline data for me as I just have no idea what im doing with these, ive looked around and there seems to be a lot of DIN 5480 spines that have been generated but I don't know if these are correct or if the file attached even conforms to DIN 5480, its just an area I have no clue about,

If somebody can do this I would be very grateful, I would be looking to use the IGES/STEP/DXF/DWG to cut the male and female shafts I am manufacturing for my racing car so I assume it would have to be correct WRT fits and tolerances, there are some 108 joint CAD files on this site but not knowing the origin of the data I didn't want to cut very expensive parts using them,

If you have any questions or need more data please ask, the attached file is a small part of the drawing that was sent over,

Thankyou in advance
