What would be a good fair price to change the bellows on a 87 454 magnum alpha 1? Lets use Merc parts, and what would be the ball park price? I am in the Detroit area. Is it just as easy to take this task on myself, and save tons of $ ? I am an Ironworker who is pretty mechanically inclined, but also dont want to fudge up my recently purchased baby- baja 240 sport 
Any and all input is greatly appreciated. Thanks so much,
Tom
