Upgrade the Interior of Your Squarebody the Right Way.

If you own a 1973–1991 Chevy or GMC Squarebody, you already know — the factory interior leaves room for improvement.

The console sits too low.
The cup holders barely work.
Speaker installs usually mean cutting up your doors.

We build solutions that fix all of it — cleanly.

Blazin’ Biddles Offroad interior upgrades are designed specifically for Squarebody Pickups, K5 Blazers, Jimmys, and Suburbans. Everything we make is engineered to bolt in properly, improve usability, and maintain the classic look of your truck.

No universal parts.
No hack jobs.
No guesswork.
