Tipsy Nipper

I am restoring a 1600 VW engine and need to find or manufacture original engine studs and spacers for MK III mounting.
I attach a section of Nipper drawing no 10, and am looking for items M1600/1, M1600/2, M1600/3, plus lower stud.
Can anyone help?
Thanks

Hi David,
I may have some solid ones on the shelf............what is the airframe bolt diameter? Some were m10, some were m8.
