Shop Rare GM OEM Parts from OPGI’s Collection

At Original Parts Group (OPGI), we’ve spent decades building, restoring, and supplying parts for the classic cars we love. Because we’ve worked together for so long, you know our dedication runs deep. Over the years, we’ve accumulated an incredible collection of genuine OEM parts through our in-house vehicle builds for events like SEMA.

Originally, our team acquired these parts to support in-house R&D efforts. By studying the exact fit and finish of these original components, we engineered accurate reproduction parts for thousands of classic GM vehicles. In fact, we even bought out limited OEM inventory specifically for this purpose. Now that we have finished these builds and development, we’re opening the vault and offering these rare parts for sale for the very first time!

Why We’re Launching on eBay

Our new eBay store provides a direct link to this limited inventory. Because these are real-deal, factory-original components rather than reproductions, factories no longer manufacture many of these items.

This includes:

• trim pieces
• bezels
• badges
• interior components
• lighting assemblies
• and more…

Whether you’re restoring a show car or just looking for that perfect finishing touch, you might find exactly what you need among these one-of-a-kind pieces.

Limited Inventory – Act Fast!

Most of these items are extremely limited – sometimes just one or two units of a particular part. Once they’re gone, they’re gone. So if you see something you need, don’t wait too long to grab it!

If you’re looking for reproduction GM parts or other classic car restoration items, head over to OPGI.com where we offer a wide selection of OEM-quality reproductions that meet the highest standards of craftsmanship. Our catalog covers everything from exterior parts to interior accents, all engineered to restore your car to its original glory.

Same Trusted Team, Same Quality Service

Even though these parts are being sold on a new platform, they’re still being shipped directly from our warehouse in Southern California by the same team that handles orders for OPGI.com. That means you can expect the same attention to detail, professional handling, and top-tier customer support that you’ve always trusted from us.
