Old coming out.Plugs are 2 piece design.Got to get some some penetrating oil(PB Blaster or something like that)and let it soak before trying to take them out.There are some threads on other sites and a TSB from Ford on the problem.Try to do a search
Thanks for all the optimistic views from everyone.
As for details,its no monster build
