How hard and what is involved in replacing the brake booster on an 80 vette?

typically the "hard" part is disconnecting and reconnecting the brake pedal and associated assemblies
under the hood is easy

Yeah, thats it.. disconnecting the rod from the pedal..its tight in there..the booster comes off easily

Thank you for the info. Does the steering coumn have to be dropped to complete the job or does it just make it easier to do?
