Not included: Upholstery, power window hardware (unless added), speakers (unless added), door handles, or armrests.
Important: Panels ship in raw gel-coat finish.

Fitment

Speaker options
Each panel has a built-in 6.5-inch speaker opening. Fesler Morel speaker kits are available as add-ons — no metal cutting required to install. Two configurations available:
Power windows
These panels are engineered for power windows. Fesler offers complete power window kits with GM motors and a billet 2-way switch kit with everything needed for installation. Both are available as add-ons at checkout.
Door handles and armrests: Fesler billet is strongly recommended.
These panels are specifically engineered to integrate with Fesler billet door handles and armrests. Both can be wrapped to match your interior and are sold separately. Stock or aftermarket handles may be used but will require modification to the panel and latch mechanism for proper fitment.
Installation
- Skill level: Intermediate. Direct OEM-style replacement with minimal adjustment on a standard factory Squarebody cab.
- Test-fit: Test-fit both panels before upholstery or paint. Trucks with prior door work may need minor trimming.
- Speaker install: Fesler Morel speaker kits drop into the 6.5-inch opening without cutting any metal.
- Power windows: Install power window kit before finalizing panel position and sending to upholstery shop.
- Door handles and armrests: Fesler billet hardware installs cleanly. Stock handle integration requires modification.
- Professional installation recommended, particularly for power window wiring, speaker wiring, and final upholstery fitment.
Shipping
- Ships as oversize. Weight is listed as dimensional weight for shipping purposes.
- Both panels are inspected, packaged, and shipped in-house from Phoenix, Arizona.
- Lead time may apply. Contact us before ordering if your build has a hard deadline.
Frequently asked questions
What is Style B?
Style B is an updated door panel profile for the 1973–1986 Squarebody. It uses the same extra-strength fiberglass construction, wood inserts, and full door coverage as the original Style panel — with a refreshed look. Style B is in stock and shipping now.
What years and trucks does this fit?
These panels fit the 1973 through 1986 Chevrolet and GMC Squarebody standard cab truck. They are not designed for Suburban, Blazer, or crew cab configurations without modification.
What are the wood inserts for?
Wood inserts are built into each panel for added rigidity and installation support. They give the panel additional strength and make mounting hardware more secure during installation.
