I almost forgot, try Dale's Musclecar Parts in Bracebridge, Ontario. He makes a genuine effort to supply stuff of interest to Beaumont owners. Try him first, in fact.

Another good possibility is Ray at SPECIAL INTEREST AUTOS in Oakville, Ontario. He specializes in Ford parts but he can get decals for all cars. I have bought many decals from Ray Nadeu for my many Chevys and present Pontiac for many years now. If it is being reproduced then he can get if he does not already have it in his inventory. Cheers.
