55.2-59 Brake return spring

[my56chevytruck]

This can apply to about any year of truck, but having a 56 I wanted to stay with this forum. I have my MC mounted to the firewall so my brake pedal goes thru it, and have been noticing my brake pedal lagging some on return so I need to mount a return spring, do you have pictures of how you did it and mounted the spring to what part of the brake arm to what did you mount the spring to?? Pictures would be appreciated if you have them. Thanks
