Hood Tach Placement
Short answer: To place an aftermarket hood tach (all references as if sitting in the driver’s seat — “right” = toward hood center, “front” = toward the bumper):
- Left rear corner of the tach to the left edge of the hood: 4.75″
- Left rear corner of the tach to the rear edge of the hood: 3.75″
- Right rear corner of the tach to the rear edge of the hood: 2 13/16″
Fudge these slightly to get the tach face square to the car’s axis. The required hole in the hood is 3.75″, offset (not centered under the tach) to clear the housing and wires below.
