The Beaumont was built in Canada alongside the Chevelle. They were sold at Pontiac-Buick dealers in Canada; however they wern't officially Pontiacs. The Pontiac asociation was always implied, never stated. They were Chevelles with Tempest dash assemblies. Sometimes they used Tempest Custom interiors, sometimes Lemans-GTO interiors, sometimes Chevelle interiors, and sometimes a combination. They used Tempest steering columns but Chevelle steering wheels & consoles. Often they used a different front facia that carried the Pontiac split grille theme. Almost always they matched the Chevelle model for model (the Chevelles offered in Canada anyway). Hope that helps.
I have a 67 Beaumont. The body panels are essentially the same as the Chevelle. They may differ slightly around the tailight lenses as the Beaumonts don't wrap around. As mentioned the grill area is two piece. My interior is all Chevelle except the dash which is Pontiac Tempest/Lemans/GTO. The Beaumonts though did not have wood grain dashes. The drive train is Chevrolet except the call the small block "Econo-jet" and the big block "Econo-flame". The Beaumont used different wheel covers whether on ralley rims or stock rims. Finding parts was not a big deal except the proper "derby caps". ANy questions please drop me a line or check cdnclassics.chevelles.net .
