The height and depth measurements are always +/- 1/8" of an inch. Length measurements will normally run 3/16" longer than the stated length measurement. This is the industry standard for all underbody boxes. The reason for the variations in industry standards is due to the varying width of the coil steel from the steel mills. They run it +/- 1/8" onto the coils. If a specific length, height or depth is required, we can build them to exact sizing at no extra charge but we need to know in advance if you have any maximum size requirements. I'm happy to hear that you were able to use them. We would have happily replaced them if you had let us know. Thanks for your purchase!

Can you be more specific? What part of the assembly do you need measurements of? Most side gate latch assembly are the standard interchangeable size. Please call us at 909-254-2800 to get specific measurements.
