I came across the 1990 Chevrolet brochure and found with the Caprice series (with the of course door mounted shoulder belt):
- Caprice Classic Sedan
- Caprice Classic Brougham Sedan (Padded full vinyl roof)
- Caprice Classic Brougham LS Sedan (Padded landau-style rear roof treatment)
- Caprice Classic Wagon (Also availabe Estate package with faux wood grain applique)
I'll scanned these vehicles at IMCDb page and make appropriate comment there
I'll also will add appropriate model here as time permit as well
