The colour 29 years ago will differ from today. You will either have to go somewhere where they use the computer colour matches or find a paint
shop that matches by eye. I can suggest a place in Toronto for the latter, but instead recommend you call a couple of interior decorators in your area to see who they use for paint
and colour matching.
An alternative would be to get replacement decals from Tom A who has recently posted the availability of parts such as decals elsewhere on the forums.
