Shim stud extensions

[66chevy PROSTREET]

does anyone know if someone makes some extensions (for upper a-arms) to be able to add more length to the studs to be able to add more shim/spacers to get more positive camber??

i am maxed out on stud length and i need to get more positive camber at the ride height i want to be at.

if no one makes some, i will have some made at a local machine shop. i have a pretty good desgin ideas
