Brake Booster

I have a 1984 Eldorado Bairittz Convt. and I need to replace the brake booster. The manual states to remove the master cylinder, disconnect the pushrod and then remove booster-to-crowl nuts. Well thats the problem. Is it easy to remove the booster and what do I need to remove inside the vehicle in order to get to the pushrod and booster-to-crowl nuts? Thank you in advance for your input :)

Man, its dead in this forum. I asked for help and I didn't get it. Whats Up !!!!

The booster is held to the cowl from inside by four nuts. Up under the dash; not easy to get to.
The push rod is connected to the brake pedal, held by a clip. My be a cotter key, or clip.

Thanks for the reply, but a little to late. I got some advice @ Cadillac-Lasalle.com they really helped me out.
