Under Body Specs 67 thru 69 Camaro and Firebird Unibody Dimensions.
These measurements are modified from Fisher Body Specs, to correct printed errors in the Fisher Body manual. All measurements are center to center unless otherwise noted. Car must be setup on a level surface, for accurate measurements. A Tram Gauge is recommended for accurate results. Factory Tolerance plus or minus 1/8 inch. Note: Your car may measure out differently. This is due to difference in measuring methods used. Most important is that the car is square and level to its self. Be sure to read the Notes
