Much more than making brackets.

The fuel system needs to deliver the right amount of fuel for the amount
of air going into the engine. If there is not enough fuel, the engine
blows up. In addition to that the supercharger heats the air; hotter air
requires more fuel.

The stock fuel delivery system is designed to supply fuel for a stock
engine; a supercharger can increase the amount of air by 50% or more.

The K-Jetronic is a mechanical injection system which is not easy to make
precision modifications to compared to modern electronic fuel
systems. The Island system has some plumbing designed to make the
existing system supply approximately the right amount of fuel for turbo
operation, and works well enough. You could probably adapt that for use
with a supercharger.

As an alternative a Haltech or other stand-alone EFI computer could be
installed.
