Any step by step instructions on converting auto-4spd?

i was looking at those Fibreglass humps, but not sure how they would hold up in my car (daily driver- will be parked outside through rain)...ive done a little reading through the mopar chassis manual about 4 speeds, so its becoming a little clearer...my dad said the install shouldnt be a problem...i just got to gather all the parts....also, anybody know where i can find a quicktime scattershield for cheap?
