Re: help on 1979 traveler
That's a '79 Scout Traveler, not to be confused with the Travelall which was discontinued after the 1975 model year.
I would recommend calling a couple of the IH Scout vendors, like Super Scout Specialists, Anything Scout, A.T. Scouts, Scout M.A.D.ness, Light Line of Louisiana, etc. Some or all of those guys should have them.
The only seal that I know of right off hand that's not available is the upper liftgate seal, where it meets the top of the tailgate.
