Early Bronco NP435 4-Speed Transmission Tunnel Cover with Boot

When you swap a 4-speed NP435 into your Early Bronco, you’re left with a much larger opening in the transmission tunnel—and that’s where the NP435 Transmission Tunnel Cover with Boot comes in. This setup includes a precision-formed steel tunnel cover and a heavy-duty shift boot to close up the hole, giving your Bronco a clean, finished interior while keeping out dust, dirt, noise, and heat. Whether you’re deep into a swap or cleaning up an older install, this cover and boot combo delivers factory-style function with trail-ready protection.


  • Designed for NP435 Swaps: Built specifically for Early Broncos with a NP435 4-speed manual transmission conversion.

  • Includes Steel Cover & Boot: Comes with a custom-fit tunnel cover and shifter boot for a clean, sealed interior.

  • Seals Out Debris: Prevents unwanted dirt, dust, noise, and heat from entering the cab through the transmission opening.

  • Factory-Like Fit: Designed to align properly with NP435 positioning—no guesswork or poor-fitting universal parts.

  • Finishing Touch for Interior: Essential for any 4-speed conversion aiming for a clean, complete look.


Finish your NP435 4-speed swap right - this steel tunnel cover and boot seals up the floor, keeps the cab clean, and gives your interior a solid, finished look.

The cover and boot filled the transmission cut out perfectly. Looks great and about 20 minutes to install.

This covers the Np435 perfectly and matches up with the existing tunnel very well. I painted the pice and screwed to the tunnel . Looks sharp and improved the lines of the Np435 install. I also installed a gear banger during the re-do.
