had the info I was seeking!! You are correct about my work place. I'm an electrician working on oil rigs in the North sea. we have 14 days on and 28 days off!!! I do have a shop manual for the bird. It's a must. I don't know how many birds we have over here, but the club has about 200. members. also have a 1957 Cadillac Fleetwood and a 1948 Plymouth Coupe.
