Hi, Chuck, To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

This fits those vehicles with 1 headlight per side. If I read your question correctly you are looking for the quad headlight application with 2 per side

Not sure if this will answer your question but I bought a similar item for a 83 GMC Jimmy that has equal size stacked lights. The frame I received had 2 differing light opening. The right part was listed under 83 Chevy Blazer. Square body interchangeability.

No, you would need the bezels for the Silverado trim package
