When my brother needed brackets for his '36 Dodge he could not find any so he made his own. He had a local water jet company do it for him and since it took more than one attempt to get the brackets just right they cost more than I paid for the kit I bought.
I'm not willing to take my truck apart to make a pattern off its caliper brackets. Mine is not using Camaro stuff anyway so it would not be what you want.
If I was the one who designed and was selling the bracket kits I'd be offended if someone simply copied my design in order to make their own. That's taking money away from the people who figured out how to solve the problem.
