Put a Crow harness in my plane last year but didn't save the measurements. The shoulder straps are pretty short because your shoulders are right against the roll bar where they secure to. If I recall correctly, the lap belt was longer than typical. I measured using my old belts and when I called to order they seemed concerned I hadn't measured correctly because they were odd. They fit perfectly and I love them.
One thing that you'll deal with is the bolt hole for the lap belt. The hole is too large for the bolt so I carefully reduced the diameter of some washers on the deburring wheel then squeezed them in.
