Drummer, under the dash follow your brake pedal up to the top, and you will find a clevis that hooks to the brake pedal. There should be a spring that hooks to the clevis pin, remove the spring from the clevis pin, and pull the pin out.That should be the last thing to unhook. At the factory they use a chalk compound on the booster where it mounts to the firewall. This is to keep exhaust gases from entering the cab. You will need to pry on the booster to get it loose. I know my was very hard to get off, but you will get it.
Glad to hear about your new Luv, hope to see pictures, it sounds great.
