Direct-Fit Design

The ATM7404 ships as a complete, preassembled dash panel precision-engineered to match the factory instrument cluster opening on 1967-1972 Chevy and GMC full-size trucks. The injection-molded panel uses all original factory mounting locations, so installation requires no cutting, drilling, or irreversible modification to the vehicle. The factory dash comes out, and the InVision panel goes straight in.

The panel also incorporates integrated rear cutout guides for up to four additional 2-1/16-inch or 2-5/8-inch auxiliary gauges. Builders who want to add a wideband, EGT, transmission temperature, or boost gauge have dedicated cutout positions already engineered into the panel.

Display and Gauge Overview

Frequently Asked Questions

Does this dash panel truly require no cutting or drilling?
Correct. The direct-fit panel matches the exact factory instrument cluster opening on 1967-1972 Chevy and GMC trucks, using all original mounting holes. No modification to the factory dash structure is required.

What speed signal sources does the speedometer support?
The speedometer calibrates to OEM factory sensors, square-wave electronic sensors, sine-wave electronic sensors, and GPS-based speed signal, covering virtually every drivetrain configuration.

Will this unit work with my aftermarket fuel sender?
Very likely. Seven selectable resistance ranges cover standard GM senders, Ford senders, and common aftermarket units. Most solid-state senders are not compatible.

Can I program the odometer to match my existing mileage?
Yes, during the initial installation window only. The unit allows odometer programming within the first 500 miles of operation. Once past that threshold, the odometer locks and cannot be changed.

How many cylinders does the tachometer support?
1 through 12 cylinders. Compatible with stock ignitions, points-based ignitions, MSD and other aftermarket systems, and LS and other engine swaps.

Do I need a CAN Bridge for a classic truck build?
No. The system is standalone. The included sending units handle oil pressure and water temperature. CAN Bridge modules are optional for builders running 2008-or-newer OBD-II swapped engines (ATM-9113) or Holley EFI systems (ATM-9111), sold separately.

Does this work with an LS engine swap?
Yes. Use AutoMeter P/N 5284 for the tachometer signal interface. The speedometer accepts the LS VSS output as a square-wave input. Oil pressure and temp use the included dedicated senders.

Can I add more than six gauge inputs?
No. The six channels are fixed. However, the dash panel includes cutout guides for up to four 2-1/16in or 2-5/8in auxiliary round gauges that mount physically in the panel alongside the display.

Does this fit both Chevrolet and GMC trucks?
Yes. Chevrolet and GMC full-size trucks from 1967 through 1972 share the same dashboard housing platform, covering C/K pickups, Blazer, Suburban, and GMC Jimmy (1970-1972).

How does the audible alarm system work?
A built-in speaker fires an audible alarm alongside a visual on-screen warning when any programmed threshold is crossed (low fuel, low oil pressure, high water temperature, or low voltage). All set-points are user-programmable via the joystick.
